Mitt Romney and Barack Obama spent yesterday jabbing back and forth at each other, with Romney on the stump in Pennsylvania and Obama calling for Romney to release more of his tax returns. Gee, I wonder where he got that idea from?

Rick Santorum met with a group of conservative leaders in Virginia in what was described as “a late attempt to rally the right and block Mitt Romney’s nomination from becoming inevitable.”
