Who Can Beat Obama In 2012?

So the run up for 2012 is fast approaching and I’ve been contemplating, who could beat Barack Obama? Right now, I’m not seeing anyone beating him. While I see many good candidates on the Republican side I just can’t see any being able to seriously beat Obama. Huckabee put it well on GMA, you cannot underestimate the incumbency:

“I think he is going to be tough to beat,” Huckabee said.
