The Trumpistan rollercoaster is running at full tilt. Paul Ryan, the Republican speaker of the House of Representatives, declared that he was “not ready” to endorse Trump. Given that Ryan is the most powerful and most popular Republican in the country, that is a blow to Trump who claims that he wants to unify the party. Trump hit back by saying that he was “not ready” to support Ryan’s agenda.

Trump also reversed policy on accepting big donations and revealed that a former Goldman Sachs partner would help him raise money. That is a stunning development as, over the past three months, most of the people I have talked to at Trump rallies have listed the tycoon mostly funding his own campaign as one of the reasons that they were supporting him. Trump needs a lot of money to compete against Hillary Clinton, but he also risks losing some of his core support unless he can convince people, once again, that he is Houdini. Read more

Polls in Indiana close at 6pm and 7pm depending on where you live in the state. Ted Cruz will be hoping that the protester with a “Cruzin for a Luzin” sign outside his rally in La Porte on Sunday had it all wrong. But the omens are bad for the Texan who once looked like he might cross the finish line in first place in the relatively conservative state. Read more

Ted Cruz is a world-class debater. But he met his match in Marion, Indiana when he engaged a Donald Trump fan who said the senator would find out when the Hoosier State votes on Tuesday that “Indiana don’t want you”. Cruz has been campaigning furiously, in what could be his last chance to derail Trump from getting the delegates needed to win the GOP nomination without a contested convention.

Donald Trump and Ted Cruz are poised for one of their final duels in Indiana on Tuesday when the Hoosier State will help decide if the Texas senator can block the New York businessman from clinching the Republican nomination. John Kasich has basically pulled all of his resources out of the state as he makes his long-shot pitch in Oregon and California. Read more

John Boehner has been out of the spotlight since he was ousted as the Republican Speaker of the House last year. One of his most memorable appearances since then came via a photo he tweeted of mo​wing his new lawn in Florida. But the former Ohio congressman is back – with a vengeance. In an interview at Stanford University, he told people what he thinks about Ted Cruz, the Texas senator who is backed by the same Tea party members who dethroned him. Read more

Less than 24 hours after he was trounced by Donald Trump in the Acela primaries, Texas senator Ted Cruz made the unorthodox move of naming Carly Fiorina, the former Hewlett Packard boss, as his running mate – something that in most elections only happens when the presumptive nominee, which Cruz certainly is not, arrives at the convention.

Speaking in Indiana which votes next week, Cruz gave a few reasons for the move, including the need to “give the American people a clear choice”. It came across as a desperate effort to change the narrative after he lost his mathematical path to reaching 1,237 delegates – the number needed to win the nomination on the first ballot at the convention on Tuesday. Read more

The race for the White House has moved to the northeast with five states – Pennsylvania, Maryland, Connecticut, Rhode Island and Delaware – served by the so-called “high-speed” Acela train voting on Tuesday. In the Republican race, Donald Trump is hoping to build on the momentum from his big win in New York last week as he tries to reach the 1,237 delegates needed to avoid a contested convention.

To help understand the convoluted battle for delegates, we have compiled an explainer on contested conventions. If you’re confused, believe me you belong to a big club, including Trump who has been slower than Ted Cruz in learning the ropes. Trump recently brought in Paul Manafort, a veteran Republican operative, to help him win the shadow battle for delegates, but there are signs that the billionaire is unhappy with Manafort’s efforts to make him sound and appear more presidential. Read more

Bernie Sanders brought his “Feel the Bern” revolution to Gettysburg where Abraham Lincoln delivered one of the most famous speeches in US history. Playing tag-team with Hawaii Congresswoman Tulsi Gabbard, a rising star in the Democratic party, he recited part of Lincoln’s 1863 Gettysburg Address: “This nation under God shall have a new birth of freedom, and that government of the people, by the people, for the people shall not perish from the earth.” Watch his speech for yourself.

Sanders frequently talks about the need to reform the criminal justice system. In Gettysburg, he lambasted a system that allows private companies to run prisons. He also reminded the packed room about the infamous “kids for cash” scandal in the state that involved a businessman who ran prisons bribing a judge to send more business – jailed kids – in his direction. Read more

Donald Trump is hoping for a big victory in the Republican primary in New York tomorrow to erase the painful memories of the past few weeks, which have included losses to Ted Cruz in Utah and Wisconsin. The Texan has also vacuumed up, and locked in, delegates in states in ways that will help him if the GOP presidential battle ends up in a contested convention. Read more

After a rough and tumble debate with Hillary Clinton on Thursday night in Brooklyn, Bernie Sanders flew overnight to Rome for a conference on inequality where he was scheduled to meet Pope Francis. Unfortunately for Sanders, whose trip cost him two days of valuable campaigning time in New York: the pontiff had to cancel the meeting to travel to Greece.

Instead of a photo-op with one of the strongest voices for tackling inequality, Sanders ended up sitting beside Evo Morales, the leftist president of Bolivia, whose appearance in the same shot probably does not help Sanders an awful lot with American voters. Read more

Donald Trump has had a tough few weeks. He was hammered in Utah and Wisconsin and failed to win any delegates in Colorado which has a complicated multi-tiered electoral process that the tycoon says shows that the system is “rigged” against outsiders like him. But he is heading into the New York primary on Tuesday with a commanding lead of more than 30 points over John Kasich and roughly 35 points over his main rival, Ted Cruz. Trump also learned today that Florida prosecutors have decided not to prosecute his campaign manager, Corey Lewandowski, who had beencharged with “battery” for allegedly manhandling a female reporter at a rally.

Cruz appeared with his wife Heidi, a Goldman Sachs banker, and their two young daughters at a CNN town-hall debate last night. The presence of the children helped humanise Cruz who is sometimes compared to a vampire and has almost no friends in Washington. This is just one of the jokes about Cruz in the US capitol: “Why do people take an instant dislike to Ted Cruz? Because it saves time!” Read more

Welcome to the Scottish edition of #Trumpistan. Donald Trump is busy wooing the people of Scotland. The tycoon, whose mother was born on the Isle of Lewis, this week penned his inaugural column for The Press and Journal, a newspaper in Aberdeen, near where he built a controversial golf course.

“When I just arrived on the scene in Aberdeen, the people of Scotland were testing me to see just how serious I was – just like the citizens of the United States have done about my race for the White House,” writes Trump, before continuing with, “I had to win them over … Well, Scotland has already been won – and so will the United States.” Read more

Paul Ryan, the popular House Speaker, poured cold water on the idea that he would rescue his party from Donald Trump and Ted Cruz, the main rivals for the Republican nomination, at July’s convention in Cleveland. Trying to end speculation about his ambitions, he said he would not accept the nomination should the Republican race end up being decided by a contested convention in July.

“Let me be clear. I do not want, nor will I accept the nomination for our party,” the 46-year old Wisconsin congressman declared following a trip to the Middle East where he was repeatedly quizzed about the 2016 race. Read more

Donald Trump has a big poll lead in New York ahead of the April 19 primaries in the Empire State. But the mogul revealed on Monday that he has already lost the votes of two key supporters: his children Ivanka and Eric. The pair were not registered as Republicans and failed to meet the registration deadline. “They had a long time to register, and they were, you know, unaware of the rules, and they didn’t register in time,” Trump told Fox News. “So they feel very, very guilty.” Watch the interview in which he also poured cold water on suggestions that he would pick Ivanka as his VP.

Trump lashed out at the GOP electoral process after Ted Cruz won most of the delegates in Colorado over the weekend. The Texas senator notched up 34 delegates in the state where voters are excluded from a process in which party members pick the representatives that will head to the Republican convention in Cleveland. “That is not the way that democracy is supposed to work,” Trump railed. “The system is rigged. It is crooked.” Read more

We know that Pope Francis was unimpressed with Donald Trump after the pontiff accused the mogul of not being Christian because of his stance on immigration and wanting to build a wall on the US-Mexico border. But is the Pontiff leaning towards Bernie Sanders? The Vermont senator announced with pride on Friday that the Vatican has invited him to speak at a conference about social and economic issues – one of his signature subjects. But it turned out the invitation did not come from Pope Francis himself, so we might have to hold our breath a little longer. The Vatican story was a nice break for Sanders who has spent much of this week trying to explain why he was unable to explain one of his main goals – to break up the banks. Here is our story on what Sanders wants to do.

The Democrats and Republicans are focusing on New York, which holds its primary on April 19. Trump is back in force on Twitter after recovering from his disappointing loss to Ted Cruz in Wisconsin. He reminded people on Friday that running for president is not the only thing he does every day. “So great to be in New York. Catching up on many things (remember, I am still running a major business while I campaign) and loving it!” Read more

Donald Trump had a terrible night on Tuesday, although you would not know that from his Twitter feed, which went uncharacteristically dark for hours after it emerged that Ted Cruz had crushed him in Wisconsin, aka the Badger State. Looking beyond the headline results should make the tycoon even more concerned, as his Texas rival has started making inroads into some groups – lower-educated and lower-income voters – that had been fertile terrain for Mr Trump.

The creator of this Trump colouring book may need to add some kryptonite to the superhero image of the billionaire on the cover. As for Mr Cruz’s image, he likes to make a virtue out of the fact that he is anti-establishment (which has inspired T-shirts like this), but the Texan may need to change his tune now that the establishment is coming on board to defeat Trump. Read more

Donald Trump is clearly not satisfied with simply being the frontrunner for the Republican presidential nomination. Watch the video he tweeted out today, which suggests that he sees himself as Luke Skywalker. His Republican opponents, who are scared stiff that he will destroy the party, might prefer to say Anakin Skywalker.Trump is facing the prospect of losing to Ted Cruz in the Wisconsin primary on Tuesday. That would increase the odds of a contested convention in July, which in turn would raise GOP hopes that the establishment could parachute in someone to save the party. Increasingly, the whispers in Washington are about Paul Ryan, the Speaker of the House of Representatives, who has denied wanting the job, but has chastised Trump on several occasions recently. Read more

Ted Cruz is famous for having almost zero friends in Washington. But the Texas senator seems happy with that situation and is not about to add Donald Trump to his circle even after the New York property mogul visited the US capital to attempt to build bridges with the Republican Party. Appearing on Jimmy Kimmel Live! on Wednesday night, Cruz was asked whether he preferred President Barack Obama or Trump more. Here was his response:

“I dislike Obama’s policies more, but Donald is a unique individual,” Cruz told the comedian. “If I were in my car and getting ready to reverse and saw Donald in the backup camera, I’m not confident which pedal I would push.” Read more

The Easter Bunny has been unkind to Donald Trump. On Tuesday his campaign manager, Corey Lewandowski, was charged with “battery” after a reporter alleged that the former state trooper had yanked, and bruised, her arm at a campaign event. Trump defiantly dismissed the claims and urged people to watch the video of the incident, which police in Florida police released after charging Lewandowski.

In a campaign that has made House of Cards seem tame, it transpired that one of the lawyers representing Lewandowski resigned as a top prosecutor in Florida in 1996 after being accused of biting a stripper. Speaking to reporters on his plane, Trump said he had urged Lewandowski to fight the charges. Texas senator Ted Cruz and Ohio governor John Kasich, the other Republican contenders, slammed Trump over the case. Read more

Donald Trump escalated his ugly feud with Ted Cruz over the two Republican candidates’ wives on Thursday, retweeting a composite photo of Melania Trump, a former model, and an unflattering image of Heidi Cruz.

The Texas senator replied by calling Trump a coward: “Donald, real men don’t attack women. Your wife is lovely, and Heidi is the love of my life.” Speaking on television later, Cruz continued: “It’s not acceptable for a big loud New York bully to attack my wife … It is an action of a small and petty man who is intimated by strong women”. Read more
