(CNN) - Scott Brown will be back on the campaign trail Monday in Massachusetts - not for himself but for the fellow Bay State Republican who hopes to take a page out of the former senator's political playbook.
Brown was a little known state lawmaker in January 2010 when he upset Martha Coakley, the commonwealth's Democratic attorney general, in a special Senate election to fill the remainder of the term of longtime Democratic Sen. Ted Kennedy, who died the previous summer.

Fast forward to present day and Gabriel Gomez, a businessman and former Navy Seal, is hoping to follow in Brown's footsteps. Gomez is the GOP nominee and the underdog in Tuesday's special Senate election in Massachusetts against longtime Democratic Rep. Ed Markey. The winner will serve the remaining year and a half of the term of Democratic Sen. John Kerry, who stepped down earlier this year to become U.S. secretary of state.
Gomez's campaign confirms to CNN that Brown will team up with Gomez at the candidate's final rally Monday night, on the eve of the election. Markey has led in the public opinion polls, with the two most recent surveys released this week by the Boston Globe and the Boston Herald putting Gomez down by double digits. But a pro-GOP survey released Thursday indicated a much closer contest.
Brown, who lost the Senate seat last November when he was defeated by Democrat Elizabeth Warren, passed on running in this special election. But if he had run, Brown said in an interview earlier this week with a local TV station in Boston that he "absolutely" could have beaten Markey.
Brown has signed his name to fundraising emails to help Gomez, and said "when I can do things, I'm happy to," but he added in his interview with Fox 25 that the Gomez campaign has "a different strategy, trying to do it and be his own person, and you know, show off what his credentials are and try to do it on their own."
While Gomez has had such big GOP names as Sen. John McCain of Arizona and former New York City Mayor Rudy Giuliani stump with him on the campaign trail, Markey has teamed up with all the heavy hitters from the Democratic Party. In the past couple of weeks President Barack Obama, former President Bill Clinton and first lady Michelle Obama traveled to Massachusetts to help out Markey. Saturday Vice President Joe Biden makes the trek to the Bay State.
The winner of Tuesday's election will succeed William "Mo" Cowan. Democratic Gov. Deval Patrick appointed his former chief of staff to serve as interim senator after Kerry stepped down.
The Democrats currently hold a slim 54-46 majority over the Republicans in the Senate. Their coalition includes 52 Democrats and two independent senators who caucus with the Democrats.
