The rumors that Newark, New Jersey, Mayor Cory Booker will run for a U.S. Senate seat in the Garden State are still rumors, but Booker's recent formal filing of papers to create a campaign political action committee brings those notions closer to reality.

An anonymous source spoke to NJ.Com and said that the mayor may run, but that talking about a potential race helps to raise money that Booker can use in helping President Barack Obama get reelected.

Deep-pocketed supporters of the Democratic Party have been urging Booker to consider a Senate race. The mayor does have a political action committee, chaired by Bari Mattes, Booker's longtime fundraising adviser and former City Hall employee, that is looking into the possibility.
