Not a lot, judging by the latest poll by Labourhome.
A poll by the group - designed to “take the temperature of Labour activists” gave the highest scores (this is relative) to David Miliband at 5.48, Alan Johnson at 5.45 and Hilary Benn at 5.43.
The worst were Gordon Brown at 3.37 and Alistair Darling at 3.35.
Remember: these are Labour activists.
