"the punditry favored Giuliani; he was a frontrunner, but not at all considered a shoo-in the way Hillary is."
That is all I was claiming. Hillary is an unusual case; I've not seen this level of "shoo-in" before.
Also, just to be clear, I'm not making grandiose claims that I know something about the race, nor am I claiming that this is somehow identical to previous situations [1]... it's more that I know that something isn't true: The punditariat is wildly overconfident, and their current confidence in their beliefs is wrong. Even if they are ultimately correct, they're still overconfident right now. The echo chamber does that.
[1]: It never really is, and there's a certain amount of anti-inductiveness to similar situations in politics: http://lesswrong.com/lw/yv/markets_are_antiinductive/ If you see a similarity that favors X, in general, so do X's opponents, and they're likely to do something that will, as a side effect, break the similarity somehow.
