Vice President Joe Biden says the Democratic Party isn't dead and will retain not just the Senate but the House on Election Day.
The country's No. 2 Democrat was the headliner Saturday at a rally for William Keating, a county prosecutor running to succeed Rep. William Delahunt.
National Republicans believe Keating's opponent, Jeff Perry, may have the best chance of claiming one of the 10 Massachusetts congressional seats for the GOP on Tuesday. A victory would imperil the House majority that Biden and President Barack Obama need to pass their legislative agenda.
Vicki Kennedy, widow of Sen. Edward Kennedy, urged the crowd to support Keating. And Delahunt, who's retiring, said the best way to honor him is to allow him to pass the baton to Keating.
