Two parties have power of any sort in the US. How are you going to get this "conservative party" to do anything? Win one race. The "Constitution Party" has been around for years and has done nothing unless you count Bob Smith who was only elected as a Republican.
There are good Republicans. Tim Walberg. Mike Pence. With primaries, more folks like that can win, starting at the local level.
You and Jimmy Carter may be comfortable with a Romney presidency, but I'm not.
