Democrat Elizabeth Warren is up by five points over incumbent Republican Scott Brown in the latest WBUR/MassINC poll of the Massachusetts senate race. That's a near-total reversal of the BUR poll last month, which had Brown up by four on Oct. 9.

In fact, Warren has been trending upwards in most recent polling. The New York Times' FiveThirtyEight blog has Warren up by four in an average of recent polls. The blog, which uses advanced statistical modeling akin to baseball sabermetrics (think Moneyball) gives Warren an 89 percent chance of winning the election.

But Brown's got some significant energy on his side as well. He's been barnstorming the state with political luminaries like Senator John McCain and today won the Boston herald's endorsement.

So what do you think? Who has the momentum coming into the final two weeks of the election? Do the polls in liberal-leaning Massachusetts mean anything to you, or will Brown's high-profile support sway the electorate? Give us your prediction in the comments below!
