(CNN) - The widow of the late Sen. Ted Kennedy teamed up Saturday morning with the Democratic candidate trying to serve the last three years of her husband's term.
Vicki Kennedy joined Massachusetts Attorney General Martha Coakley to shake the hands of voters in Boston. Kennedy formally endorsed Coakley last week and appears in a campaign commercial for Coakley that began airing on television Friday.
The canvassing for voters with Kennedy was the first of nine campaign events for Coakley Saturday, as she picks up her get-out-the-vote efforts in advance of Tuesday’s special Senate election.
A Suffolk University Poll, released Thursday night, suggests that Coakley is locked in a dead heat with Republican state Sen. Scott Brown. A Boston Globe survey released last weekend indicated Coakley had a 15-point lead over Brown, but other recent polls, including several partisan surveys, suggested the race was much closer. Thursday, two well respected non-partisan national political analysts, Charlie Cook and Stuart Rothenberg, rated the race a toss-up. The race has dramatically tightened up from early December, when Coakley appeared to hold a large lead over Brown in a state that Democrats traditionally dominate.
Kennedy is just one of a string of high-profile Democrats to campaign with Coakley in the closing days of the campaign. Former President Bill Clinton teamed up with Coakley at rallies in Boston and Worcester on Friday. Sunday, President Barack Obama flies to Massachusetts to join Coakley at a get-out-the-vote rally.
Brown is on a campaign bus tour Saturday, with eight scheduled stops. Friday, he had help from his own high-profile surrogate, as former New York City Mayor and 2008 GOP presidential candidate Rudy Giuliani joined Brown to greet voters. Former Massachusetts Gov. Bill Weld, a fellow Republican, rides with Brown for a portion of Saturday's bus tour.
With recent polls indicating that Brown is winning the battle for independent voters, Democrats need to motivate their base to show up and cast ballots come Tuesday.
