I predicted the 65% figure for Milliband before even opening the tab. I guess most of this forums US D avatars voted EdMil and Labour because they're to the left of most Dem supporters, who would probably go Clegg or Cameron. I can see most GOP going Farage.
Even if I were more to the center, Cameron's policies have clearly been a colossal failure. And Nick Clegg is an idiot. Farage is, of course, a crypto-fascist. So Labour is the only sensible option.
And even setting aside policy differences (which are, as you pointed out, total failure in their own right) Cameron as a leader has been completely awful and uninspiring as well. He's shown no ability to lead
his own party, let alone a coalition or an entire country. I can't imagine how anyone who isn't just a complete hack/demagogue could deny that Labour is basically the least offensive option at this point, even if Ed is completely milquetoast.
