U.S. Senate Candidates Take Final Swing Through Mass.

The candidates in Massachusetts' U.S. Senate race are making a last swing through the state.

Republican U.S. Sen. Scott Brown, on a nine-stop bus tour, went to his field office in Lowell, where he called voters to make a personal pitch for their support.

Brown urged several dozen campaign volunteers to continue to work hard until the polls close Tuesday. Brown said his close race with Democratic challenger Elizabeth Warren "is about turnout, people getting out to vote."

Warren made a campaign stop in Boston's Dorchester neighborhood with the sons of the late Sen. Edward M. Kennedy, Ted Kennedy, Jr. and former U.S. Rep. Patrick Kennedy.

Patrick Kennedy said his father admired Warren's tenacity.

Warren also invoked the late senator, saying "no one ever had to ask on what side Sen. Kennedy stood."
