I'm sure the Labour Party's internal polling would back up my opinion of David Miliband. Labour MP John Mann told the Sunday Politics programme last week that he was told again and again and again on the doorstep that Ed was not of prime ministerial quality and that David was superior.
Yes, but people saying that probably don't remember that clearly what he was actually like as a politician, they're just saying that because he's the person most often mentioned as an alternative leader in the media. It has very little to do with how he'd actually have performed if elected leader.
If (and I accept it's an "if") the Tories' scaremongering about SNP influence was decisive in Labour's defeat, then the Scottish disaster was important even though the SNP were likely to back Labour in a hung parliament situation.
I disagree (well, if by "credible" you mean someone like David Miliband). If anything I suspect it would have been the other way round. I suspect I'd have been in the Green column with him as Labour leader.
Possibly, but there isn't really much evidence either way. I still suspect that most 2010 Tory voters were basically happy with the government, and electing David Miliband as leader wouldn't have got away from the way that the Tories, aided and abetted by the Lib Dems and Liam Byrne's sense of humour, were allowed to develop the "mess Labour left us" narrative in the immediate aftermath of the 2010 election.
I'm not talking about UKIP actually winning Labour seats (obviously, as it didn't happen) but people who might otherwise have voted Labour voting UKIP in Lab/Con marginals. How big a factor it was I don't know, but it was there to some extent, and while I don't have a particularly good feeling for why this type of voter votes the way they do I don't see David Miliband as the sort of Labour politician to attract them back.
