All that money didn’t profit Romney in Iowa all that much. If Gingrich and Perry dropped out, that would leave a lot of folks looking for a new home.
If Gingrich and Perry’s inclusion in Iowa were that signification (for Santorum), why didn’t they do better?
I get your point about having funds to run negative adds about Romney, but I’m not sure if that was Romney’s problem, or Santorum meeting as many Iowans as he could, was.
Romney didn't worry about Santorum because he can knock him off anytime.
I don't think any more should drop out until we get a conservative not-romney that has staying power. Santorum hasn't been tested yet.
