A good point by point take down can be found at Think Progress, David Broder’s Continuing Embarrassment. Josh Marshall explains Broder here:
People think of Broder as the 'Dean' of the Washington press corps because of things he did in the 60s and 70s. But the man he is today is much more a product of the long conservative ascendancy of the last three decades -- an ascendancy still very much alive in the town's journalistic and editorial elite. You can hear the animus more and more sharply in this columns as his inability to grasp the political moment becomes more and more clear.
Paul Begala give it to Broder with both barrels over at The Huffington Post. Go read the entire thing but here is a teaser that's right on the money.
Why Reid? Because Reid has been one of the few politicians with the courage to speak the plain, unvarnished truth to power, and the hallmark of Mr. Broder's career has been to suck up to power. Reid calls Bush a liar. Broder can't handle the truth.
