Greg Corombos of Radio America and Jim Geraghty of National Review appreciate more Democrats defending the private equity business after the Obama campaign rebuked Cory Booker. They also like a new American Crossroads ad that rips Obama’s record without savaging Obama. In addition, they scold an Arizona official for abandoning a campaign promise and for very publicly demanding proof of Obama’s birth. And they unload on The Washington Post for openly speculating how a Mormon militia attacking western settlers in 1857 might impact Romney’s campaign.
