As you may have seen on other sites by now, Gallup has an interesting poll on the Clinton/Obama “dream ticket” :

Only 42% of Democrats nationwide want Hillary Clinton to be the Democratic vice presidential nominee if Barack Obama wins the presidential nomination, while 55% think he should pick someone else. By contrast, the majority of Democrats — 58% — would like to see Obama nominated as vice president if Clinton heads the ticket.
. . .
The reason for the disparity is that a relatively small number of Obama supporters — just 29% –favor Obama choosing Clinton as a possible running mate. Seventy percent say they’d rather he choose someone else. In contrast, a majority of Clinton supporters — 53% — would want Clinton to choose Obama for vice president if she is nominated.

I think Chris Bowers has the most accurate explanation for Gallup’s findings :

Hillary Clinton has repeatedly floated the idea of Obama being her Vice-President, and as such her supporters are following her lead in thinking he would be a good choice. By the same token, Obama has never floated Clinton as his Vice-President, and has even repudiated the idea of a “dream ticket” on multiple occasions. As such, his supporters are following his lead, and looking elsewhere for a a possible VP choice.

Kinda pathetic to think that one of the best chances Hillary has of catching up to Obama is to try to convince people that a vote for her could be a vote for Obama as well. It makes sense if you think about it. Considering the way the Obama campaign has broken fundraising records, attracted millions of new voters, and packed stadiums all over the country, if the stars align and Hillary Clinton were to somehow squeak by the with the nomination, she’d still need Obama on the ticket. The same isn’t true in reverse, so it shouldn’t be too surprising that Obama supporters aren’t enthused by the idea of rewarding the person who’s spent the last few months trying to destroy their candidate.
