Much of the criticism of John McCain so far is that he's too much like George W. Bush. "McSame" is the word that liberal opponents are trying to make stick. I think it's apt, but it also applies--at least in this case--between McCain and Dick Cheney.
It's now five years since the Iraq War--or occupation if you prefer--began. Prior to the beginning of the conflict, and for some time after it started, Dick Cheney repeated "we will be greeted as liberators." He was absolutely adamant about it. Apparently, John McCain felt the same way, and still does.
