It was simply his turn as flavor of the month in Iowa. Now that he’s had a chance in the spotlight, a lot of people have had a better look at his record and don’t like the look of him as much as they once did. Just like Perry, Cain, and Gingrich.
I don’t agree. Santorum had campaigned hard in Iowa. There is more to this than the flavor of the month, and I’d bet that it has to do with Ron Paul.
