She's fighting for 1 or 2 reasons, or maybe both
1--she's in the hole by millions of dollars and, absurd as it sounds, the longer she stays in the race, the more donations she can rake in and pay off her debts...she's under no obligation to return any pledged money she receives, so if anyone gives her some today and she drops out tomorrow..you might as well have lit a match to your money..
2--She's staying in to force Obama, somehow, to select her for V.P. I can't imagine she wants to be Veep because the Veep only has power to break a deadlock in the Senate. She'll be just a figurehead as a Veep working for Obama...she won't be part of his cabinet.
If I can level some criticism at Obama it's that he and Edwards didn't campaign in Kentucky together. What was the point of John Edwards going to Michigan to speak on behalf of Obama if they didn't do anything together? Why not just release a press release? Edwards and Obama could've campaigned in KY and at least cut the loss to 5-10pts.
I just think Obama has the money to campaign in these racist states and he's making a mistake by not doing so. Some of these hillybilly idiots will actually "wake up" and realize that the nation is swelling behind Obama and they need to wake up or risk being kicked aside for the next 8 years...
Obama got Senator Byrd's endorsement! Even racists have a pragmatic side! He was a card-carrying member of the KKK (wasn't he Grand Wizard too?)
Obama's bank account is spilling over...he has a warchest and I think he should've spent some of it...
