Democratic Congressman Edward Markey and Republican Gabriel Gomez are keeping up busy schedules on the final weekend before the special election for the U.S. Senate, with both campaigns trying to rally supporters and mobilize for a get-out-the-vote effort.

Vice President Joe Biden urged Markey supporters at a rally in Dartmouth Saturday to go to the polls on Tuesday and called on as many other Democrats to do the same. Biden was the latest Democratic heavy-hitters to campaign for Markey, following visits by President Barack Obama and former President Bill Clinton.

Biden mocked Gomez's claim to be a new kind of Republican, saying Republicans "don't get it."

Gomez, a former Navy SEAL, had more than two dozen campaign stops planned before Tuesday. He said during a stop in Wakefield that his field effort was in "phenomenal shape."
