This is a combination Obamateurism, as there are a couple of moments from yesterday’s campaign appearance that just doesn’t make sense. On one hand, Obama says he doesn’t know anything about Scott Brown and his record:

Obama never once uttered Brown’s name, and admitted that he wasn’t too familiar with him.

“I’ve heard about some of the ads that Martha’s opponent’s running,” Obama said. “He’s driving his truck around the Commonwealth. He said he gets you. That he’ll fight for you. That he’ll be an independent voice. I don’t know him. I don’t know his record. I don’t know whether he’s been fighting for you up until now. But here’s what I do know. I want a senator who’s independent too … and here’s what I know: Martha will do so. She’s got a track record of doing so. I know there are things in which she and I disagree. She doesn’t just call herself independent. She has the character to be independent. I hear her opponent is calling himself independent. But you have to look under the hood.”

He doesn’t know Brown’s record, but he has no problem characterizing it for the audience:

Obama recited Coakley’s common refrain that, “As a legislator he (Brown) voted with Republicans 96 percent of the time.”

“It’s hard to suggest he’s going to be significantly independent from the Republican agenda,” Obama said.

D’oh!

But on the other hand, he knows enough to say that Brown will vote against taxes:

You’d better check under the hood, because from everything I’ve seen, Martha’s opponent would have voted against those taxes!

D’oh!

She would have voted against those tax cuts!

D’oh!! You can almost hear Martha Coakley saying, “You can shut up now, Mr. President.” And listen to the crowd go silent as he muffed the easy play. Obama would have been better off sticking to his first argument, which is that he didn’t know what he was talking about, rather than continuing to open his mouth and make it obvious.

Got an Obamateurism of the Day? If you see a foul-up by Barack Obama, e-mail it to me at [email protected] with the quote and the link to the Obamateurism. I’ll post the best Obamateurisms on a daily basis, depending on how many I receive. Include a link to your blog, and I’ll give some link love as well. And unlike Slate, I promise to end the feature when Barack Obama leaves office.
