Christie is scheduled to hold a press conference in Trenton to announce the New Jersey Environmental Federation's endorsement of his candidacy, according to a source close to the Christie campaign. The group is breaking with the Democrat in the race, Gov. Jon Corzine, whom they backed in the 2005 election.
The New Jersey Environmental Federation is a non-profit, action-oriented organization developing a growing coalition of community, environmental, student and labor organizations able to act on a broad range of environmental issues, according to a description on their Web site.
Corzine is facing a tough bid for re-election, but recent polls suggest he's recovering. Three survey's out over the past week indicate that the battle between Corzine and Christie, the former federal prosecutor in New Jersey, is basically a dead heat, with Independent Christopher Daggett grabbing a small percentage of the vote.
Another environmental organization, the Sierra Club, has endorsed Daggett, a former state Environmental Protection Commissioner.
