It's like a runaway train, and if you look at the history of spending excess, it's always sky high with a republican president.
I still hear this victory in Iraq crap out of McCain, and as Vietnam vet he should remember how that ended 30 years ago. I would want to get out of that as fast as I could to stop hemoraging blood and money, as we clearly know Iraq had nothing to do with fighting terror or 9/11. Insurgents, (those who don't want the occupation), surged after the US fell down on any promises it might have made, so any military action is just to stop the bleeding from past mistaks.
But the real republican agenda is more money channeled into the same large corporations and the changes in McCain's public promises have changed to copy Obama as his popularity overshadowed his own. The same people are in place influencing the same individuals despite what face McCain and Palin want to put on it. He is looking for a compromise which by nature doesn't exist. That's why he's been vague on issues, he's trying not to make promises he won't keep.
