Western Mass Ed Markey supporters gathered at the Senate candidate's campaign headquarters on Island Pond Road in Springfield Friday.
A UMass, Lowell/ Boston Herald poll shows Markey widening his lead over Republican Gabriel Gomez.
Markey has a 20-point lead with the support of 56 percent of the 312 likely voters polled.
Still, Markey says he'll be ramping us his campaign these next few days.
"Overconfidence reads complacency. And we are just in the opposite situation in our campaign. We are working 24/7. We are taking nothing for granted. We don't believe the polls," Markey said at Friday night's rally.
Former U.S. Senator Scott Brown has been campaigning for Republican candidate Gabriel Gomez.
Gomez will be in Western Mass this weekend.
The special election will take place Tuesday.
