What we are witnessing right now is what a McCain presidency would be like -- herky jerky, bouncing from crisis to crisis, overreacting at every step.
It's taken him exactly ten days to go from the economy is strong to we're heading into the Great Depression and must stop the campaign.
But nothing has changed other than the polls, and that's why it's impossible to take this gamble seriously.
McCain can see that he cannot win the presidency unless the campaign narrative changes dramatically, so he's decided to roll the dice.
After all his talk of bipartisanship, John McCain has decided to make an intensely political move. He does not have a plan, but he's willing to drag the country through his personal drama, no matter the cost, just so that he might win the presidency.
McCain wants to demonstrate his leadership skills, but instead he's demonstrating beyond any doubt that he is temperamentally unfit to be president.
