President Obama burned Mitt Romney today with a political version of a "yo' mama" joke. Romney's message is so simplistic, he said, it could "fit on a tweet and have some characters to spare." Wha-bam! Basically, the president argued while in Maryland, Mitt and the Republicans' political message is based on blaming Obama for the state of the economy. "Because folks are still hurting right now, the other side feels that its enough for them to just sit back and say, 'Things aren't as good as they should be and it's Obama's fault," he said.
