McCain is only in it for himself. Afterall, he has the media on his side, because the media keeps calling him a "media darling". Even if something going on in Washington doesn't involve McCain, McCain is the "go to guy" as far as the media is concerned.
Unfortunately for the Republicans and Conservative America, there are people like McCain, and now pat buchanan again, who are so bitter, petty and self absorbed, they will sell out the nation for their own purposes.
