Romney class warfare video — Amazing stuff. The leaked video, like the Obama 2008 remarks about “bitter” folks who “cling to guns or religion” observation, has gone viral, our colleague Philip Rucker reports.

Romney, speaking to wealthy backers, blasted “the 47 percent” of Americans, solid Obama voters, he said, as thinking they are “entitled to health care, to food, to housing, you name it. . . who pay no income tax” and won’t take “personal responsibility” for their lives.

Big problem, of course is that a decent chunk — say maybe 30, 40 percent or so? — of those 47 percent “losers” are, by definition, actually part of Romney’s base.

But maybe there’s a silver lining here? If someone on Romney’s team reminds him he shouldn’t insult his own voters, maybe they’ll re-focus the campaign? Still seven weeks to go, after all.

The Constitution’s 225th — 215 newly naturalized citizens celebrated the happy birthday Monday after taking the oath at the National Archives, Dan Zak reports. (There were supposed to be 225 people there but 10 folks didn’t show up.)
