trouble that lies beneath that? >> well, this goes to the conversation you were having with martha about the bus tour. it is very interesting, if you start to see president obama struggle further with white working class voters in the rust belt states in the upper midwest, that suggests deeper problems. one thing to look for, and we saw this in 2010 to a certain extent, prominent democrats who seem to be running away from the president or don't want to be seen campaigning with him. heidi high camp running for senate in north dakota cutting a ad that distances herself from obamacare despite the fact she supported it before. remember back in 2010, joe donelley, who was running for house then, is running for senate now, said basically cut this ad saying he didn't want to be identified with the president on immigration. if you start to see more of those kinds of moves by moderate democrats, i would suggest that the president may have trouble in those areas. bill: yeah. we'll see if the list grows or not.
