Democrat Jon Corzine (search) and Republican Douglas Forrester (search) criss-crossed the state Sunday to rally support for their gubernatorial campaigns, as polls showed Corzine holding a slight lead.

Corzine focused on urban areas, scheduling visits to Trenton, Newark and Paterson, which traditionally vote for Democrats.

Forrester made stops in Williamstown in the state's rural south before spending the rest of his day in GOP strongholds along the New Jersey shore.

Corzine was joined by U.S. Sen. Barack Obama (search), D-Ill., at Shiloh Baptist Church in Trenton, where Obama told the congregation he was there to help his "homeboy." Obama said the central Illinois area where Corzine grew up values "hard work, decency, looking after someone's neighbor."

Corzine said after the service he hoped to discuss his plans to lower property taxes and other issues in the final days before Tuesday's election.

"I really think it's important to stay on the issues, because elections are about the future," he said.

Forrester, greeting families at a mall in Freehold, said he thought the confrontational televised debate with Corzine on Saturday night was perfect to show that his opponent does not have the grasp of issues needed to be governor.

"I had a chance to get after Senator Corzine about things he still doesn't understand," Forrester said.

Corzine and Forrester are vying to succeed acting Democratic Gov. Richard J. Codey (search), who assumed office last November after the resignation of James E. McGreevey (search) in the wake of a gay extramarital affair.

The two candidates, both multimillionaires, have already spent a combined $70 million on the race, making it the most pricey in state history.

Recent polls that show Corzine holding onto a slight lead, at the same time national Democratic leaders seem to be paying more attention to the race than their GOP counterparts.
