the other point when you get to a general election is that most general election voters aren't highly engaged policy focused voters. they really vote on a gut feeling. a president who's at a 29% approval rate willing have a hard time getting to majority. >> can i have you weigh on the big poll that came out of the democratic race in iowa. it has elizabeth warren overtaking joe biden by to points. that puts her in the lead. we should note within the margin of error. it's kind of a virtual tie as well. do you think this is specific to iowa or is there a greater story here about the race? >> noo, warr, elizabeth warren the move. she has momentum in the race. that doesn't mean she'll inevitably be the nominee but we could see the beginning of a momentum where she could be the front-runner by the end of the year, maybe sooner. that has its perils but she's running a strong campaign.
