I have seen how Bob Barr and Ron Paul are ignored by the current Republicans. I have not determined which third party is the best but I do know that the Republicans and the Democrats have too many similar traits regarding the removal of individual freedoms and the acceptance of our membership in the UN for me to continue support for the Republican Party.
It's a free country...do what you want. But I will do everything in my power to increase Conservative strength where I think it can actually accomplish some positive good...in the GOP.
