Your the only republican who still makes that point.
Iam sure McCain feels the same way you do.
First off, I'm not a Republican and secondly, when you see massive inflation, bread lines, thousands upon thousands of homeless and a greater then 15% unemployment rate, then you can claim that the fundamentals of the economy are NOT strong. We're doing tons better then a lot of other countries would do faced with this situation.
Not only was McCain's campaign poorly run, but it suffered from the economic crash, an already anti-GOP enviroment, a perfectly run campaign by his opponent, and hurricane Palin, who in the end hurt Obama more than she helped.
The polls have proven that Palin didn't really hurt McCain, she actually helped him gain a few points.
