WOOD-RIDGE - Obama Senior Advisor David Axelrod said he doesn't expect Newark Mayor Cory Booker to muzzle himself for the remainder of the general election.

Nor does he want Booker to stay underground, he told PolitickerNJ.com here at a rally where he formally endorsed the re-election of U.S. Rep. Steve Rothman.

"No, I don't think so," Axelrod said, when asked if Booker should sideline himself after saying he felt nauseated by ads on both sides of the aisle, including one by Obama's messaging department that blasts Mitt Romney's ties to Bain Capital.

"We disagree, but to the extent that he clarified his remarks, I think it's fine," said the president's senior advisor.
