Hillary as Obama running mate in 2012? I don't think so - yet someone's floating the story. Trial balloon? Why on earth does someone think she'd entertain an assignment like that? To be set up as the successor in 2016? No way any party these days wins three presidencies in a row so that ain't it. She is herself an Obamaphile and will do whatever's necessary to preserve the cause? That would shock me - what wouldn't surprise is idea of her going to bed every night reveling in the sweet revenge of watching Obama disappoint all and sundry. Naw, this is either some rogue story or maybe something Obama's people have floated to test response [possibly from Hillary herself] since they're no doubt fretting about Dear Leader's chances in 2012.
update: Hillary has come out and firmly denied it.
