By a knockout, Joe Biden was the more effective, better-informed vice presidential candidate Thursday night.

Granted, Sarah Palin did not look like she was channeling a duncy Tina Fey. Palin looked far more confident than many people had expected. Her folksy approach to answering questions did get old rather quickly, though.

Overall, Biden's strengths overwhelmed Palin's.

Examples:

-- Biden gave more complete and convincing answers on how he and Barack Obama would respond to the nation's economic problems.

-- Biden was far more effective at telling Americans what, exactly, he and Obama would do in the areas of health care and in getting the nation out of Iraq.

Palin, on the other hand, wandered all over the place on several occasions.

In fact, it appeared she had been overprepped: She would be answering a question and a little light seemed to go off in her head, sending her in a completely different direction.

Example: She talked at several points about "energy independence" and the "greed and corruption of Wall Street," even when they had nothing at all do with the topic at hand.

Palin did not melt down during the debate, so John McCain's campaign team will claim that was a victory.

But Biden was far more effective at appearing ready to become the next vice president of the United States.
