Change is a powerful message, it worked here in Australia for getting rid of the old conservative prime minister, and McCain certainly does fit the picture of the decrepit old angry conservative who is desperate for the GOP to cling to the White house no matter what. All Obama needs to do is push this message that McCain just represents the old guard and nothing will change under him. McCain supports the 'rich first' policies of the GOP which have impoverished America and screwed the economy just as Reagan did.
