HAMDEN, Conn. (CBS) — The latest Quinnipiac University poll shows that New Jersey voters favor the Democratic incumbents in the upcoming general election.

Maurice Carroll of the Quinnipiac University Polling Institute says Pres. Obama and US senator Robert Menendez are leading their Republican challengers in this survey, conducted between July 9th and 15th.

Carroll says young voters favor Obama in huge numbers, while people over the age of 55 favor Romney.  He says that ethnicity also seems to play a role.
