Guest hosting a few weeks back on Boston's WTKK, I offered listeners the five biggest blunders in presidential debate history. I'm rooting for a debate gaffe tonight that will eclipse the following clips:

5. Michael Dukakis, 1988: CNN's Bernie Shaw's question to the wonkish Massachusetts governor begins, "If Kitty Dukakis were raped and murdered..." The rest is history.

4. George H.W. Bush, 1992: Looking bothered to be there, the unpopular president repeatedly looks at his watch and sends the vibe to Americans watching that it was time for a change.

3. Richard Nixon, 1960: In the first presidential debate in U.S. history, a sickly Richard Nixon imagines the television age is still the radio age. He sports a five o'clock shadow, wears a light suit that blends into the light backround, and sweats profusely. Make up isn't just for girls when you go under the hot lights of television.

2. Al Gore, 2000: The vice president gets a little too close for comfort as George W. Bush attempts to give an answer. If the office were weirdo-in-chief, the former vice president would have won the election in a landslide rather than lost it by a few hanging chads.

1. Gerald Ford, 1976: Sounding like a Manchurian candidate, the leader of the free world tells a perplexed New York Times scribe that there is no Soviet domination in Eastern Europe. Lyndon Johnson didn't say that the former UMichigan guard played too much football without a helmet for nothing.

John McCain and Barack Obama debate one final time tonight. Given that Obama boasts a commanding lead in most national polls, and given that debates usually aren't won but lost, what, possibly, could Barack Obama say tonight that would evaporate that point spread? How off-the-wall a statement would he have to make to transform a blowout into a ballgame? I want answers.

After the performance of Joe Biden it certainly appears that there is nothing Obama could say that wouldn't be explained away and covered up by the progressive media. Except, perhaps, if he told the truth about why he, like other leftists, hates the America of our forefathers. Something like "America must learn that it is just another country" might hurt. But he has spent a lifetime perfecting the art of avoiding saying what he believes.

What if Barack took a page out of Kanye West's book and said "John McCain doesn't like black people."
