Disaffected Republicans? Democrats welcome you.
Uh, no you don't. It's more en vogue to make fun of Republicans for killing off their moderates, but have you watched your own debates? Hillary Clinton is about the most standard liberal Democrat on the planet, and she's being painted as a corporatist by her competition. How would a candidate standing up there talking about out of control debt, too much regulation on business and cutting taxes for everyone be received?? The GOP being a bit crazier doesn't excuse the Democrats' purity tests. Face it, to be a Democratic nominee, at the end of the day, you HAVE to play the game of getting the "middle class" to the polls.
Meh. The whole "corporatist" thing is only really a litmus test for the Bernie/Occupy wing of the party. Jim Webb was probably too far to the right for the Democratic Primary electorate, but was still more at home as a member of the party than most RINOs. The only real litmus test for Democrats by now is gay marriage, and there are exceptions to that rule as well.
