You know, I’ve always thought that Pat Buchanan was a racist and an anti-Semite who wrote columns that in a not-so-veiled way presented a racist and anti-Semitic point of view. But I think I was wrong, at least judging by his most recent column, “Has Obama lost white America?” which ran last week. I’ve decided that Buchanan isn’t a racist; he just understands the mind of the average white racist. The jury is still out on whether Pat is an anti-Semite.

Buchanan’s central argument is this: the Scott Brown victory in Massachusetts is a product of racial discontent among the overwhelmingly white population of the Bay State. Just so you know, according to the U.S. Census Bureau, the population of Massachusetts is 86.2 percent white and 7 percent black, compared to South Carolina’s 68.7 percent white and 28.5 percent black.

What’s funny about this is that I almost made this exact same argument. Like my fellow columnist Jack Hunter (an unrepentant Buchananite), I lived in Boston for a spell. And during that time, one thing became crystal clear: Even when Beantown ain’t covered in snow, it’s all white. In fact, the area of town in which I lived and played, Allston and Brookline, you could probably go an entire day and never see a black person. Well, except for Mr. Butch, a street character who carried a six-string on his back. God rest his soul.

Of course, I didn’t write about my little theory. There had to be reasons for Brown’s victory other than white discontent. And there were. In fact, Jon Stewart paints a convincing case about why Bay Staters turned against the tone deaf Martha Coakley. Hint: Curt Schilling may be a Republican, but he is not a Yankees fan. His bloody sock is the reddest sock around.

But Pat has changed my mind. About the so-called Massachusetts miracle, he says that “a growing perception that Obama is biased” is a factor. He writes: “When the president blurted that the Cambridge cops and Sgt. James Crowley ‘acted stupidly’ in arresting black Harvard professor Henry Louis Gates — a rush to judgment that proved wrong — his support sank in white America and especially in Massachusetts, where black Gov. Deval Patrick joined in piling on Crowley. Deval is now in trouble, too.”

The paleoconservative adds: “Then there was Obama’s appointment of Puerto Rican American Sonia Sotomayor to the Supreme Court. Her militant support for race and ethnic preferences and her decision to deny Frank Ricci and the white firefighters of New Haven a hearing on their case that they were denied promotions they won in competitive exams because they were white caused 31 GOP senators to vote against her.”

Buchanan also has a theory about where those white voters were in 2008, back when Sen. John McCain needed their votes: “In 2008, the working and middle class had had a bellyful of the Bush-McCain Republicans. They were seen as pro-amnesty for illegal aliens and pro-NAFTA, when U.S. workers had watched five million manufacturing jobs disappear in a decade — and reappear in China. They were willing to give Obama a chance because Obama had persuaded them by November he was not just another big-spending utopian liberal.”

Maybe I’m wrong here, but it wasn’t that these anti-McCain, anti-immigrant, Archie Bunkers cast votes in favor of Obama over the Republican Party’s candidate. Nope. These voters either didn’t vote or they cast a ballot for third partiers like Chuck Baldwin or Bob Barr.

But things have changed. With the rise of the Tea Party movement, the Angry Archies have a reason to get their fat asses off of their well-worn recliners. And now that W. is out of the White House and the Republicans no longer in control of Congress (and the Iraq War becoming a distant memory), it’s safe once again for middle-age right-wingers to denounce the federal government and bitch and moan about the injustice of everything, just like they did during Bill Clinton’s reign.

And for some of these Bunker Boys, the fact that a black man is president makes this all the easier.

Thanks for clearing that up, Pat.
