Davis has run as a Democrat before, but he only ran on one issue: protectionism. I believe he tried to get considered for the Republican nomination this time. He's kind of crazy, but he has a lot of money, which is a big head start when the election is only in a couple months.
Let the protectionists be Republicans. There is nothing progressive or liberal about something so archaic and outdated. Any top economist will tell you it's not even a viable policy in our increasingly inter-connected global market. I can only hope the teabaggers let this guy become Hoffman 2.0 and we pick up yet another upstate New York district that was once solidly GOP.
