henders henderson. the obama camp stepping up calls on mitt romney to release his tax returns as well. when we look at this debate, what does this buy the president with the average voter? >> it buys them another bullet point, another plank in their argument that mitt romney is out of touch and mitt romney is somebody who think that is he doesn't have to play by the rules. as we know, presidential candidates for years, for decades have released their tax returns. mitt romney's own father, george romney, in the 1960s, released a dozen years of his tax returns. and president obama has released tax returns going back to 2000. i think we're going to hear a lot about this. mitt romney has filed for an extension. he has released his 2010 tax returns. but this is going to be something that i think the president and his team are going to hammer all summer, going into the fall, until he releases these tax returns.
