HRC has only had to withstand the media attacks this long because she's been around longer.  And because she's been around longer, we have a lot of stuff to pick on. 

So I guess what Hillary's camp can say is that Obama hasn't been around as long, and therefore there hasn't been enough time to pick his bones dry yet.

But, it's funny.  He gets his bones picked dry this year over all the stuff we've found out about him this year, and he's still ahead in the polls and the votes.

Hillary gets her bones picked dry this year over stuff she's saying this year, and she's dropping in the polls.
