Unlike 2008 when Obama could campaign on vague promises of "Hope and Change" and a penchant for voting "present", this time around he will have to answer for his actions
I don't think it much matters who runs against Obama in 2012. Unless his opponent throws in the towel like McCain did in 2008 - just think what George Bush would've done with Obama's Marxist background and politically radioactive associations with Bill Ayers, Rev. Wright and Tony Rezko - I can't imagine anyone losing to the most vulnerable reelection candidate in American history.
