The morning after, it's even easier to see exactly how Joe Biden won Thursday's debate -- and precisely how Sarah Palin faltered.

The highlights:

-- Biden wasn't smug, he wasn't condescending and yet he hammered home point after point, such as linking John McCain to President Bush's failed policies.

-- Biden stayed on point. He didn't wander around after moderator Gwen Ifill asked a question. Whether it was Iran, the bailout or other topics, Biden answered what he was asked.

-- Biden talked about foreign affairs like he knew the trouble spots of the world and how he and Barack Obama would handle them.

On the other hand:

-- While Palin didn't commit huge gaffes, she wandered all over the place in answering questions. It was noticeable, and made it clear Palin's knowledge of many topics was skin-deep.

-- Palin tried too hard to appeal to "Joe Six Pack" and her efforts to connect to the "middle class" -- words McCain hardly mentioned in his debate -- came off strained.

-- Finally, Palin only once or twice actually had the goods in attacking Biden or Obama. One successful thrust was, ironically, to praise Biden for opposing some of Obama's anti-Iraq war policies. Other than that, Palin didn't lay a hand on Biden.
