JOHN HEILEMANN: Trump, Carson, Cruz and Fiorina add up to 53% in Iowa.

MIKE BARNICLE: 53%? So that means that if I lived in Iowa, I would want to know where each of thos members of that 53% lived, and I would want to live as far away from them as possible, because there is something seriously wrong with the Republican party if those people combined have a majority of the voters.
