Polls suggest mixed effects of Clinton on ticketBasically it tells us what we already expect: Clinton's a polarizing figure. Obama putting her on his ticket would help him among her supporters, but hurt him among independents -- but then again, the places where she'd have a significant impact are states he'd be unlikely to win in the first place.
Had a chat with a friend yesterday where she pointed out the wrongheadedness of suggesting that Clinton's supporters should just fall in line and back Obama, as if he's entitled to their votes. I can relate -- I voted Nader rather than Gore in 2000, and never liked the suggestion that Gore somehow should have gotten my vote by default despite his awful campaign that year. (Of course, it bears repeating that I live in Arizona and my vote doesn't matter anyway; I might feel differently if I lived in a swing state. But I might not.)
On the other hand, the "I'll vote McCain because I just HATE OBAMA SO MUCH" attitude put forward by a vocal minority of Clinton supporters is cutting off the nose to spite the face. First of all, I think they're blaming him for sexist comments that he himself had nothing to do with; secondly, it seems like people concerned with sexism probably shouldn't be voting against reproductive rights. Come down to it, I don't think there are any valid policy reasons for a Clinton supporter not to embrace Obama.
All that to say, it IS the Democrats' job to convince people to vote for them, and they shouldn't make the mistake of just expecting it as an entitlement.
Polls do make clear how divided Democrats are over adding Clinton to the ticket. Half or more Democrats liked the idea in recent polls, but Obama's supporters are less enthusiastic than hers.
And there you have it: a scientific poll showing that Hillary Clinton supporters are more supportive of Hillary Clinton than Barack Obama supporters. Thanks, Gallup!
