(CNN) - President Barack Obama's hitting the campaign trail later this month - not for himself, but for fellow Democrat Jon Corzine.
The New Jersey governor's re-election campaign team announced Wednesday that Corzine will be joined by Obama at a rally at Rutgers University in New Brunswick on Thursday, July 16. The White House confirmed the event.
While Obama has headlined seven political fundraising events this year, this will be the first campaign rally he's attended for a fellow Democrat since taking over as president in January.
A new poll of New Jersey voters suggests this year's gubernatorial battle between incumbent Corzine and Republican challenger Chris Christie may be tightening up a bit.
A Fairleigh Dickinson University survey released Wednesday indicates that Christie has a 6 point lead, 45 percent to 39 percent, over Corzine, with 15 percent undecided. Christie had a 9 point lead over Corzine in a Fairleigh Dickinson University poll in April. But the poll also indicates that only one in four questioned say Corzine's doing good or excellent job as governor.
Christie, considered a moderate Republican, led Corzine by 10 points in a Quinnipiac University survey released earlier this month.
National Republicans are gunning for victories in New Jersey and Virginia, the other state with a gubernatorial contest this year, as they try to rebound from their poor showing in last year's elections. In Virginia, the Democratic governor is term-limited and can't run for re-election.
