EWING, N.J. (AP) — New Jersey's two major-party candidates for U.S. Senate have spent their second debate arguing over how best to jumpstart the economy.

Sen. Bob Menendez, the incumbent Democrat, and Republican challenger Joe Kyrillos, a veteran state legislator, stuck mainly to their respective party's talking points during their one-hour debate Wednesday sponsored by radio station 101.5 FM.

While addressing such issues as health care and illegal immigration, they were most animated when arguing over the economy.

Menendez asked what his opponent has done to create jobs during his 24 years in the Legislature while Kyrillos said the federal stimulus program added nearly $1 trillion to the national debt.

The candidates spent several minutes describing how they would help the middle class, but both struggled to define who constitutes the middle class.
