WASHINGTON (CNN) - President Obama hits the campaign trail Thursday - not for himself, but for fellow Democrat Jon Corzine.
The president is the main attraction at a rally in Holmdel Township, New Jersey, for Gov. Corzine, who's fighting for re-election this year.
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 poll of New Jersey voters released this week suggests Corzine trails Republican challenger Chris Christie, a former federal prosecutor, by 12 points. The same Quinnipiac University survey indicates that six out of 10 Garden State voters approve of the job Obama's doing as president.
The rally was originally scheduled to be held at Rutgers University in New Brunswick, New Jersey, but the Corzine campaign says the event was moved to an outdoor amphitheater to accommodate a crowd larger than originally expected.
"The president looks to Gov. Corzine as a friend, somebody who was head of the campaign committee for Senate Democrats when he was running in 2004," White House Press Secretary Robert Gibbs said Wednesday.
