How are you protecting America by refusing to vote for McCain, thus handing the government to the Rats on a silver platter?
Answer: you’re not.
If people who take your approach would simply admit that they know very well that, by not voting for McCain, they make it much more likely that Obambi will be elected, and that (for whatever reason) they are okay with that, that at least would be a needed expression of personal responsibility for the impact of one’s vote or nonvote.
I have no influence in what direction the Republican Party goes. The fact that they have chosen to follow the Progressives line of thinking makes them responsible for the possibility that Obama could become the elected candidate, not me.
If you find their behavior objectionable then I suggest that you contact the executives in charge. I realize it is easier to try to blame a man with principles, but this time that line of action isn’t going to be effective.
