Here's the thing...I don't have any pretenses about McCain. I don't expect much out of him that I would like.
I know what I will get for sure with Barack Hussein Obama. This guy scares me as much as if Osama Bin Laden were running himself. If we were talking Hillary vs McCain, my thoughts would be different. I just can't let a guy, who can recite the Muslim call to prayer, with a perfect Arabic accent, calling it the most beautiful sound he's heard, become Commander in Chief of OUR Armed Forces because my other choice isn't conservative enough. At least he doesn't hate America.
If you think McCain will be better for Conservatism as it’s titular head for four or eight years, then vote for him.
To me that sounds like saying, McCain will save us, even if we have no active Conservatism for eight years.
If you think the nation will be better off with McCain, the RNC and Congressional Republicans supporting lefitst policy right along with the Democrats, then by all means do what you think is best.
