This is how Elizabeth Warren won a decisive victory over incumbent Republican Scott Brown on Tuesday, beating him 54 to 46 percent.

After the polls were closed and the campaign parties ended, the numbers showed how Warren swept the state. 

Exit polls from the University of Massachusetts, Amherst, showed the following:

Massachusetts Democratic operative Alex Goldstein credits a ground-breaking get out the vote effort for Warren's win.

"There’s no doubt that the way Elizabeth Warren won was through the grassroots. Her grassroots organization was unprecedented. Her grassroots turnout numbers her canvassing and turnout numbers I the past couple of months are astounding, above and beyond what’s ever been done in the state before," Goldstein said.

Gov. Deval Patrick agreed. Patrick himself had a rigorous get out the vote campaign which helped him get re-elected.

“We knocked on I think somewhere on the order of 30,00 doors the weekend before the 2010 election... Her campaign knocked on a quarter million doors on the weekend before the election," he said.
