Charles Krauthammer on Barack Obama’s clumsy lurch away from the radical left: A Man of Seasonal Principles.

You’ll notice Barack Obama is now wearing a flag pin. Again. During the primary campaign, he refused to, explaining that he’d worn one after Sept. 11 but then stopped because it “became a substitute for, I think, true patriotism.” So why is he back to sporting pseudo-patriotism on his chest? Need you ask? The primaries are over. While seducing the hard-core MoveOn Democrats that delivered him the caucuses — hence, the Democratic nomination — Obama not only disdained the pin. He disparaged it. Now that he’s running in a general election against John McCain, and in dire need of the gun-and-God-clinging working-class votes he could not win against Hillary Clinton, the pin is back. His country ‘tis of thee.

In last week’s column, I thought I had thoroughly chronicled Obama’s brazen reversals of position and abandonment of principles — on public financing of campaigns, on NAFTA, on telecom immunity for post-Sept. 11 wiretaps, on unconditional talks with Mahmoud Ahmadinejad — as he moved to the center for the general election campaign. I misjudged him. He was just getting started.
