It seems a little ridiculous for the Clinton camp to hint at wanting the vice presidency while she's still running. Why on earth would Obama pick someone who still, publicly at least, claims to be more qualified for the top spot?*
It's a nasty case of wanting one's cake and eating it, too, and on top of that it makes him look weak. If you want the job, Obama should tell Clinton, cease running for my job.
Just my two cents.
*I should clarify: I think she'd be a fine VP. But she'd have to first come to terms with accepting the position; she clearly has not.
