Overall political leanings aside, this most certainly will not help Hillary's campaign.
Unfortunately, while she may be a great leader and may have the experience and the ideas to go in and make some things happen as president, I believe there are enough people out there that truly hate her that despite what she says she is the least electable democratic candidate out there. Edwards is probably the most just because he could probably pull in more Southerners' votes for sadly obvious reasons, though Barack would probably not have a problem getting in simply due to his energizing of America's youth.
People love his message of change and one of the major blows leveled on him by his competition probably will do more to help them harm his chances. The fact that he isn't entrenched in the Washington political scene makes him seem like a fresh (and lets face it, less corrupt) face; something that is very appealing at this point to Americans. While people weren't that thrilled with Bush, Kerry was a very weak candidate for the Democrats and he most certainly couldn't motivate people to vote who don't normally. Barack on the other hand has the potential to draw record numbers of young people as well as others fed up with the American political scene out to vote. In '04 the only things energizing these people was a general hatred of Bush and his foreign policies, apparently not enough to elect a minor hack like Kerry.
That'll about do it for my political ranting, I was just moved by the Clinton article. Not sure what possessed her to cry for a national audience, though I guarantee no one is voting for her on that out of pity. As for Barack, I joined a Facebook (c'mon, I'm young like that) group a couple of years ago before he was even considering running (at least publicly) called, "Barack Obama for President (If only...)"
That's about all I'm going to say about my vote.
