Um - did I refer to you in that post? I said "Maybe" you were one of the ones, which implied asking for clarification
As for McCain, I believe you are incorrect. McCain voted to authorize W to use force in Iraq? Then, when campaigning for W to get reelected, the "greatest critic" who claimed the war would "fail" stated praised W's leadership and stated:
“But I believe, Katie, that the Iraqi people will greet us as liberators.” [NBC, 3/20/03]
“It’s clear that the end is very much in sight.” [ABC, 4/9/03]
“There’s not a history of clashes that are violent between Sunnis and Shiahs. So I think they can probably get along.” [MSNBC, 4/23/03]
“This is a mission accomplished. They know how much influence Saddam Hussein had on the Iraqi people, how much more difficult it made to get their cooperation.” [This Week, ABC, 12/14/03]
“I’m confident we’re on the right course.” [ABC News, 3/7/04]
“I think the initial phases of it were so spectacularly successful that it took us all by surprise.” [CBS, 10/31/04]
“I do think that progress is being made in a lot of Iraq. Overall, I think a year from now, we will have made a fair amount of progress if we stay the course. If I thought we weren’t making progress, I’d be despondent.” [The Hill, 12/8/05]

McCain can't have it both ways
On edit - perhaps you were stating McCain would have marched on to Bagdad in the first Gulf War. If so, so would I. But, that hardly negates his cheerleading for W's invasion of Iraq in 2003, though he double talked being against it soon thereafter and then was for it as evidenced in the above quotes.
