My choices were originally Tancredo/Hunter/Thompson. Now it appears I have to choose Romney. No way could I ever vote for creepy, crazy McCain who reminds me of the Manchurian Candidate with his radical amnesty views and other left agenda. While endorsements usually do not mean much, the fact that Tancredo - the politician I respect the most - and Ann Coulter are okay with Romney, is one factor in his favor. Romney is electable, but McCain has far too much baggage.
We can survive a RINO but we cannot survive somebody who may be mentally unbalanced and is determined to harm this country. There is no perfect candidate. I have even disagreed with Tancredo on a couple of issues.
