President Bill Clinton will head to Massachusetts this Friday to stump for Democratic Senate candidate Martha Coakley, days before she takes on Republican opponent Scott Brown in an already tough special election fight.

Clinton will headline two rallies -- the first in Worcester alongside Sen. John Kerry (D-Mass.), the second with Rep. Jim McGovern (D-Mass.) in Boston, the Democratic National Committee announced Thursday.

The former president's trip comes as the race between Coakley and Brown enters the final stretch. Polls into this week have depicted the contest as a toss-up -- some show Coakley with a double-digit lead, others show Brown trailing her slightly -- prompting both sides to throw serious campaign cash and resources to their respective candidate.

It is unclear whether other high-profile Democrats will also travel to Massachusetts this weekend or next week to make a last-minute stump for Coakley. President Barack Obama has already recorded a television spot in support of the attorney general's candidacy, but it seems unlikely he will personally make the trip to Boston this weekend.

"You know, I don't know what his plans are for the weekend," White House Senior Adviser Valerie Jarrett told MSNBC on Thursday, adding the president was focused on the earthquake in Haiti. "We have a lot of resources going to support her candidacy. She would make an outstanding senator, and she, of course, has his full support."
