If there's one thing we've learned from this year's primaries, it's this: Don't trust Washington's talking heads.

These are the people who told us, for example, that we would never nominate another senator for president; that the Clintons had the black vote locked up; and that Rudy Giuliani was the inevitable Republican nominee. Wrong, wrong, wrong.

And now, for weeks, the same pundits have been demanding that Hillary ClintonHillary Diane Rodham ClintonRep. John Katko: Why I became the first Republican lawmaker to support impeachment Can we protect our country — from our rulers, and ourselves? For Joe Biden, an experienced foreign policy team MORE drop out of the race because she's only hurting the party. But the latest Washington Post/ABC poll shows how wrong they are again.

Sixty-four percent of Democrats say Hillary should stay in the race. And 85 percent of Democrats say they're confident the party will unite behind Obama in the fall.

The same chattering class says the long Democratic primary is only helping McCain. Wrong again.

So remember this the next time you see the usual suspects bloviating on Fox, MSNBC or CNN.

They were wrong then, and they're wrong now.

Beltway pundits may speak with authority, but they don't know what the hell they're talking about.
