President Barack Obama's re-election campaign has formally opened its New Jersey headquarters.

The offices in North Brunswick opened Wednesday.

The Democratic president is seeking a second term in the November election. In New Jersey, Obama received 57 percent of the vote in 2008, compared with 42 percent for Republican John McCain.

A recent Rutgers-Eagleton poll finds 60 percent of the state's registered voters view the president favorably, compared with 33 percent who don't.

The Republican presidential field may not be settled before the party's August convention in Tampa. Former Massachusetts Gov. Mitt Romney, who has been endorsed by Gov. Chris Christie, and former Pennsylvania Sen. Rick Santorum are currently the top GOP contenders.
