"He cares about 100 percent of Americans in this country," Ryan said of Biden. "And with respect to that quote, I think the vice president very well knows that sometimes the words don't come out of your mouth the right way."
4. Martha Raddatz Took Control
PBS's Jim Lehrer was panned for being too passive during the Denver debate, but ABC's Martha Raddatz was active in asking tough questions and holding both candidates accountable.
She posed solid follow-up questions, such as when she asked Biden what military reason the Obama administration had for pulling out surge troops from Afghanistan. Or when she pressed Ryan for details on what specific tax loopholes a Romney administration would eliminate.
Overall, both sides could make a compelling case for why their candidate was effective. History tells us that vice presidential debates rarely effect the outcome of an election. But Thursday's debate was the kind of affair that you should watch if you missed it tonight.
