guess. 43% of those polled republican think that president obama is a muslim. what do you read into in that number as a rationale for how to approach the situation by donald trump? >> you look at what donald trump did. he's probably catering. there's probably a large overlap between that 40% and donald trump's 22% to 33% in the polls right now. it's probably the same people, the small minority of the broader electorate, 22%, 33% of 30% of america. it's hard to put your finger on it after 6 1/2 years of the president in the white house, two years of campaigning before that. they still believe this, there's probably nothing donald trump or anyone else can do to change their mine. this is donald trump trying to keep his support. if they believe it, he's going to say it. because that's his way of keeping his base.
