Just caught a snippet on Bill O'Reilly of Mr. O'Reilly and George Stephanopoulos discussing the admittedly remote possibilty that Sec. of State Hillary Clinton might challenge Barack Obama in a 2012 Democratic Primary. Let's go to (my recollection - which is pretty good - of) the tape:
George S: "Oh, I don't think that's likely. If there's going to be a challenge it would be more likely someone to Mr. Obama's left."
Okay, George, I'll bite. Is there anyone politically viable to Mr. Obama's left? I can't think of anyone, but you can nominate your candidates in the comments.
