Gingrich is pretty scary. To be honest all of the republican candidates are pretty scary.
The good news is that they all have done such a good job of trashing each other that they are going to look pretty bad when the primaries are over. The republicans are going to have to do a lot of work undoing the negative spin they have put on each other before the main election hits.
The one guy that is interesting to me this year is Ron Paul. Mainly because, unlike in the last primaries, this time he is up against a bunch of muppets and a centrist republican, and moreover, unlike last time, he is getting very little press.
I didn't realize that he was actually 3rd in the primaries, he is polling dead even against Obama, and he is second place in funding behind Romney.
