It was hard to tell about Ryan's preparation sometimes, because Biden kept talking over him. But as I said, I don't think this debate matters anyway.
I remember Scarbouro saying he DREAMED of Ryan as the VP pick so this race would be a REAL debate about the deficit and spending.
But now the budget wizard is forced to say that he doesn't have to explain how he will keep the candy tax cut promises from becoming deficits because he will trust the congress to figure that out. I wouldn't want to be handed an argument like that to defend as he was.
On the Biden debate, Ryan could have said assertively “Let me finish” if he was confident of his arguments. Palin had a similar problem being restrained by the McCain campaign positions. And Ryan has his own problems. I figured he was not used to debating unlike Biden who is.
