I didn't watch all of them, there were way too many, but I did watch some of them. Romney did not come off as some master debater.
I think your hate of Obama is clouding your judgement as you did mention that Obama lost the 2008 debates to McCain which couldn't be further from the truth.
I wouldn't call Romney a master debater. In fact, it was even a bit of a weakness for him in 08. But he won many of the 12 debates and other than a couple of digs by Paul and Santorum, he came out looking great. He is much more composed and on message and succinct nowadays.
And yes, McCain did beat Obama in the 08 debates; at least the last two. If I recall correctly, McCain did poorly in the first debate. But that's not to brag on McCain b/c he still sucked. That's just an endictment of Obama. Playing the blame card won't work like it did in 2008. If he doesn't develop some good tricks this time around, he will get blown out of the water.
