Today he says we are facing economic Armageddon and he is suspending his presidential campaign in order to deal with the mess.
In addition, he called upon Barack Obama to join with him and postpone Friday's presidential debate until the "Wall Street Bailout Bill" can be passed by Congress.
Last week everything was fine, now suddenly McCain's hair is on fire over this.
What happened between then and now?
Did McCain suddenly get interested in economics over the last week, study the problem and come to the conclusion that something must be done to stop another Great Depression?
Or did he see a Fox poll out today showing a 9 point turn around for Obama and a Washington Post/ABC News poll showing Obama with a 10 point lead in the race and decide that the time is ripe for a desperate Hail Mary pass/crazy stunt to try and change the dynamic of the race and save his campaign?
I'm betting the latter.
Call it another "Palin".
At any rate, Obama turned McCain down, saying the next president has to be able to do more than one thing at a time and Americans need to hear how the next president is going to deal with the mess.
A snap Survey USA poll shows a majority of Americans backing up Obama on this - they either see this as a stunt or just a bad idea.
David Letterman saw it the same way:
David Letterman tells audience that McCain called him today to tell him he had to rush back to DC to deal with the economy.
Then in the middle of the taping Dave got word that McCain was, in fact just down the street being interviewed by Katie Couric. Dave even cut over to the live video of the interview, and said, "Hey Senator, can I give you a ride home?"
Earlier in the show, Dave kept saying, "You don't suspend your campaign. This doesn't smell right. This isn't the way a tested hero behaves." And he joked: "I think someone's putting something in his metamucil."
"He can't run the campaign because the economy is cratering? Fine, put in your second string quarterback, Sara Palin. Where is she?"
"What are you going to do if you're elected and things get tough? Suspend being president? We've got a guy like that now!"
Indeed we do. Indeed we do.
