Newark Mayor Cory Booker could find himself back in President Obama’s doghouse over a misspelling.

The New York Post discovered a spelling error in an ad that Booker took out in the New Jersey directory of delegates, leaving the “C” out of “Barack.”

Booker was thought to be in the Democrat dog house following a bungled appearance on Meet The Press last spring in which Booker said he found attack ads from both candidates “nauseating” and called them a “distraction from the real issues.”

Later that day Booker released a YouTube video in which he said it is “reasonable” for the Obama campaign to examine Romney’s business record since Romney himself has made it “a centerpiece of his campaign.” Booker says his earlier remarks were intended to express his “profound frustration” with negative campaigning. And he reiterated that he believes Obama “more than deserves re-election.”

He was back in the President’s good graces when he was named to be one of 15 members of the party’s Platform Drafting Committee and will address the convention on Tuesday.
