Elizabeth Warren is a darling of the progressive movement, but she may be too liberal for her home state of Massachusetts. Warren has 51 percent support from her constituents, but only 44 percent said she deserves re-election, according to a new WBUR poll.

The poll found 46 percent of voters said it's time for Warren to "give someone else a chance." The results came as some Democratic activists have discussed the possibility of Warren running on the Democratic presidential ticket in 2020.

"No one's going to look at a 44 percent re-elect number and think that that's a good number," said Steve Koczela, president of The MassINC Polling Group, which conducts surveys for WBUR. "No one's going to look at it being close to even between 're-elect' and 'give someone else a chance' and think that that's reassuring.”

Part of the problem is Republicans really don't like Warren. Consider that Warren performed worse in the poll than Republican Gov. Charlie Baker, who had a favorability rating of 59 percent. He is well liked by Democrats and Republicans, but only 12 percent of Republicans like Warren, the poll found.

The survey reached 508 voters across Massachusetts from Jan. 15-17. It has a margin of error of 4.4 percentage points.

Massachusetts voter Peter Anderson of Wilmington said he supports Warren’s work, but her Senate seat should go toward a new candidate.

"I don't think that as a group they're doing any sort of a good job," he said of Congress. "I think they should all be replaced."

Warren, a former Harvard Law School professor, is expected to run for re-election in 2018. Baker could challenge her, but he hasn't formally announced his intention to run.

Warren could have a bigger problem winning over voters: Her age. She would be 71 by the time the 2020 presidential race came around, much older than potential rivals such as Sen. Cory Booker of New Jersey and Sen. Kirsten Gillibrand of New York. Still, that's three years younger than newly elected President Donald Trump.
