Although I am a Republican, the Tea Party is not part of the GOP. If the GOP that has benefitted from the Tea Party movement by regaining Congress fails to uphold the mandate it was given, then there will be third party movement. This is not about electing people with letters after their name, it is about putting people in office who will reduce the size of government, exercise fiscal responsibility, and abide by the Constitution and protect our individual liberties. Replacing Democrats with Republicans and getting the same results is not change.
I'm not convinced that's a wise option. Third parties rarely do well and take up space and money otherwise might change those running for office than "title" a third party.
Just can't see that as a winner for any who oppose this administration. Convince me why that would work this time around when it has failed so many other times. What's different now that would make it work?
