Does something hit Santorum before the caucus?

[M]

Can it be done? Yes. Will it? Not sure.

Iowans seem to be going for the candidates they know the least about. Perry's foot-in-mouth and Cain's alleged womanizing were unknown when they first rose. But Gingrich's consulting work, offbeat positions and multiple marriages were well, well known. If the Iowans really didn't know, they simply haven't been paying attention.

So what is it that all of us know about Santorum, but the Iowans, perhaps, don't? Perhaps his 16 point loss in Pennsylvania?

If that's not widely known, it could spread by word-of-mouth, fast.
