(CNN) - The widow of the late Sen. Ted Kennedy makes a pitch for Democratic candidate Martha Coakley in a new television campaign commercial that started airing Friday in Massachusetts.
Coakley, the state's attorney general, faces off against Republican state Sen. Scott Brown in a special election Tuesday. The race is a battle to fill out the final three years of the term of the late senator, but also at stake is the Democrat's supermajority in the Senate, and possibly the fate of the party's and President Barack Obama's drive for health care reform.
"Tuesday's election is to fill the term my husband didn't have a chance to complete. But it's not the Kennedy seat. It's the people's seat – the mother struggling to make ends meet, the father trying to find a job. My husband fought for them, and so does Martha Coakley.
"Cracking down on Wall Street and insurance company abuses. Fighting for working families. That's what Martha Coakley stands for, and I'm proud to stand with her," says Vicki Kennedy in the commercial.
The reference to "the people's seat" appears to be a push back to Brown, who said in a debate Monday that Democrats were wrong to consider the senate seat Ted Kennedy's.
Both campaigns, as well as national party organizations and independent groups, have flooded the airwaves with campaign ads.
A new poll released Thursday night suggests the race is deadlocked between Coakley and Brown. Joseph Kennedy, a third party candidate who is not related to the late senator, is also in the race.
