Keep an eye on Orange County, CA

Jim Gilchrist, the founder of the Minuteman Project, is running for Congress on the Constitution Party ticket. He has so far managed to raise more money than the Democrat in the race.
Gilchrist may actually be able to win this race, especially with the popularity of the Minutemen in conservative Orange County. It will be interesting to see if he can pull it off. However, Glichrist has already pledged that if elected he would caucus and vote with Republicans. Why didn’t he just run as a Republican?
