Both held their own very well. There wasn't a clear winner like last week's debate with Obama and Romney. Biden interrupted a lot, smirked and laughed a lot, and was generally rude and not respectful. Whether or not you like that style of debating will likely decide for you who "won". On substance, they seemed pretty even. Biden delivered a very good show for the left's base. Ryan delivered a good show for the right's base, even if it was a tad on the moderate side of things.
The only part of the debate I really had a hard time with was the abortion segment. Why didn't Ryan make it clearer that there isn't much Romney could as President to limit abortion? He could do very little, other than Supreme Court nominees and over-turning that international funding that can be used for abortion. Ryan could have made his party's point much clearer I thought. It's not like if Romney is elected all the sudden women are going to have more difficulty getting abortions. That's not the case at all.
