Is McCain a Conservative?

Is McCain a conservative?
I would say no, but more than likely, he will be the nomination. I do think he can beat Hillary or Obama. I would like to think, he would get his stones back and do a 180 on a lot of issues (taxes, immigration, etc....)
Personally, I think he is too old for the job, has been in Washington way to long.
I am utterly amazed that out of 300,000,000 people, this is the best that we could come up with.
