I personally am baffled why someone crying about loosing would make them seem a winner in somebody else's eyes, but you're correct that it's all fair play, even when the former president chooses to go on a mudslinging rampage within his own party (though it certainly feels like the old cigar-smoking back-rooms where the party bosses decide who they want and determine to "take out" everyone who opposes their choice).
My post was asserting that the water works and Bill's bullying were not the predominant factors... I think the polls were.
If I were an independent who liked one of the republicans and Obama, and Obama was up 10 points... I'd vote in the republican race just because it would seem safe that my choice was winning the democratic race.
But it also seems that we want the candidate that can appeal to the people who switch parties back and forth, rather than the candidate that only appeals to the die-hard democrats. So, in this case, if my interpretation is correct (which I obviously believe), the polls caused the more electable candidate to lose this one primary.
It's a bad day for the future of the democrats.
