Since meeting head to head for the first time this fall, U.S. Senator Scott Brown and Harvard Law School professor Elizabeth Warren will debate for a second time tonight in Lowell, Mass.

A sign of the Massachusetts U.S. Senate race's national prominence, the host of NBC's "Meet the Press" David Gregory will moderate the hour-long debate. Both WHDH-TV and C-SPAN plan to broadcast the debate live at 7 p.m. The Boston Herald will also have a live feed on its website.

While the first debate passed without a decisive victor, recent polls have shown Warren creeping ahead of Brown with only a little more than a month left until election day. Tonight's debate is expected to be one of the few remaining opportunities the candidates have to change the course of the race.
