The Republican party lost me when George Bush and the Repub congress did none of the things that conservatives dreamed would happen when we had the whole shebang. They lost me, but I'm still a member of the party and I still vote the party line, since it is still the lesser of two evils. Where else would you turn?
Join a tea party organization. Help elect tea-party candidates. All we need is a majority of tea partiers in congress and we could turn this mess around in one election. Think about it.
