BOSTON — Hillary Clinton and Bernie Sanders are neck and neck heading into the state’s March 1 primary, according to new Emerson College poll, despite the fact that the former secretary of state has garnered the support of many legislators in the State House.

Hillary Clinton is in a dead heat with the Vermont senator, with each candidate getting 46 percent of the vote and 5 percent still undecided, according to an Emerson College poll released Monday.

Nine of 19 legislators have publicly endorsed Clinton: Reps. Cory Atkins, D-Concord, James Arciero, D-Westford, Jennifer Benson, D-Lunenburg, Ken Gordon, D-Bedford and Sens. Michael Barrett, D-Lexington, Ken Donnelly, D-Arlington, Eileen Donoghue, D-Lowell, Jennifer Flanagan, D-Fitchburg, Barbara L’Italien, D-Andover.

Sen. Jamie Eldridge, D-Acton, has endorsed Sanders.

In polls conducted during the fall, Clinton had more support from voters in Massachusetts. But, now it’s a toss-up for Super Tuesday on March 1.

Donald Trump has a lead over his Republican opponents, taking 50 percent of the vote, according to the poll. That gives him a better than 3-to-1 advantage over Florida Sen. Marco Rubio; a 37-point edge over Ohio Gov. John Kasich; and a 5-to-1 margin over Texas Sen. Ted Cruz.

Rubio collected 16 percent of the vote, Kasich came in with 13 percent, Cruz with 10 percent and Ben Carson with 2 percent.

Genders align with voters in the Democratic contest, as men prefer Sanders 60 percent to 35 percent, and women support Clinton 56 percent to 34 percent, the poll said. Sanders has more support among voters in the 18 to 34 age group.

In Massachusetts, Trump’s favorability rating is an “impressive” 64 percent favorable to 32 percent unfavorable among likely GOP primary voters, according to the poll.

Likewise, both Clinton and Sanders are viewed favorably by Democratic primary voters. Clinton’s favorable/unfavorable rating is 77 percent to 21 percent, while his Sanders’ rating is 74 percent to 21 percent.

Cruz is the only candidate with negative favorability among Bay State voters. Only 33 percent see him favorably, while 60 percent see him unfavorably, the poll said.

For Democrats, the economy was the issue that mattered most to 29 percent of those polled, while 25 percent said dissatisfaction with the government was a bigger concern. For Republicans, the issues were flipped, with 35 percent expressing dissatisfaction with the government and 20 percent citing the economy.

The poll was conducted from Feb. 19 to 21, 2016. The GOP primary consisted of 289 likely primary voters, with a margin of error of +/-5.7% and the Democratic primary consisted of 417 likely primary voters, with a margin of error of +/- 4.75%. Data was collected using landline phone numbers and weighted by 2012 Presidential Election results for Massachusetts. The full methodology and results can be found at www.theecps.com.
