Rep. Sara Innamorato (D-Allegheny) holds the lead in the race for the Democratic nomination for Allegheny County Executive according to a new poll released on Wednesday morning.

Pittsburgh Works, along with Public Opinion Strategies, conducted a survey of 400 likely voting Democrats from April 29-May 1 and found 32 percent would back the 37-year-old state representative to replace term-limited Rich Fitzgerald in the position.

Pittsburgh city controller Michael Lamb and Allegheny County treasurer John Weinstein are deadlocked in second place with 20 percent, while 18 percent indicated that they were still undecided how to cast their vote. The poll has a margin of error of +/- 4.9 points. Complete polling data was unavailable as of publication time.

Innamorato has made a strong move over recent weeks after a March poll conducted by Pittsburgh Works, an organized labor-business alliance that promotes the industries that are at the  foundation of the regional economy, including energy, manufacturing, and construction. found her in the No. 3 slot (17%), trailing both Weinstein (28%) and Lamb (24%). The recent survey showed that her name recognition among Allegheny County voters leapt from 48 to 80 percent between March and May.

She also picked up the endorsement of U.S. Senator Bernie Sanders on Wednesday morning. “I’m proud to endorse Sara Innamorato for Allegheny County Executive,” said the Vermont Senator. “As a state legislator, Sara has fought for the needs of working families. She has been a consistent advocate for affordable housing, clean air and water, and to raise wages. I know she will continue to wake up everyday fighting to improve the lives of people in Western Pennsylvania.”

The winner of the Democratic primary will face off against Republican Joe Rockey in the  November 7 general election. Rockey, a former PNC executive, is unopposed in the Republican  primary.

The polling is part of the Our County, Your Vote, Allegheny’s Future initiative by Pittsburgh  Works, which is intended to encourage voters and the news media to press candidates to go  beyond campaign rhetoric and bumper sticker slogans and outline specific actions they will take  to address critical issues.
