The Milliband brothers' performance and interaction with each other is just weird. David Milliband is using Blair-esq pauses.

The two Eds interacted well. Their speech is much more fluent and sounds less coached. Up to part 3, Ed Balls seemed to be making more concrete proposals and references to the problems with current Labour politics.

Would be nice to have some paired debates and discussions: all C(5,2) = 10 of them. Get 2 candidates at a time to debate with each other and then jointly debate - on the same team - against someone else, maybe against a nasty reporter.

Here's a random order for you:

[1] "David Miliband" "Ed Miliband"
[2] "Ed Balls" "Andy Burnham"
[3] "Ed Balls" "Ed Miliband"
[4] "Diane Abbott" "Ed Balls"
[5] "Ed Balls" "David Miliband"
[6] "Diane Abbott" "David Miliband"
[7] "Andy Burnham" "Ed Miliband"
[8] "Andy Burnham" "David Miliband"
[9] "Diane Abbott" "Andy Burnham"
[10] "Diane Abbott" "Ed Miliband"

Guaranteed to be informative for revealing comradeship, rhetorical prowess, and knowledge.
