Nearly half of Massachusetts voters are ready for a new senator to replace Democrat Elizabeth Warren in the 2018 election, according to a new poll.

Forty-six percent of Massachusetts voters who took the survey, which was conducted by MassINC Polling Group and WBUR, are ready to vote Warren out of office, Politico reported Monday.

Meanwhile, 37 percent of poll respondents said they disapprove of Warren, while 51 percent said they approve. These numbers show a sharp decline from April 2015, when a poll showed that Warren had a 62 percent approval rating and a 21 percent disapproval rating.

"It's not a great place to start for her, but she still would be the favorite at this point," said Steve Koczela, president of MassINC Polling Group.

The poll was conducted from Jan. 15 to 17 and surveyed 508 registered Massachusetts voters.

While no Republican has officially announced a 2018 election bid to unseat Warren, who is known as one of the more progressive members of the Senate, retired Red Sox pitcher Curt Schilling has said that he is considering such a challenge.
