Labor Party candidate Alex Rose jumped out to an early lead Tuesday night over Republican incumbent Mike Embrescia for an at-large seat on Allegheny County Council.

Democrats were leading in seven other races in smaller county council districts.

If the results hold up, Republicans would hold just one seat on the 15-member council starting next year.

As of 10 p.m., with 58% of precincts reporting unofficial results and about 92,000 mail-in ballots counted, Rose had collected 58.2% of the votes tallied compared to Embrescia’s 41.1%.

Rose, an Erie native who lives in Squirrel Hill, earned degrees from the University of Pittsburgh. Although a member of the Labor Party, Rose said he has worked on numerous Democratic political campaigns while also volunteering on the disaster response team of the American Red Cross.

He could not be immediately reached for comment.

Embrescia, of Mt. Lebanon, was appointed this year to replace former Allegheny County Councilman Sam DeMarco, who resigned to work for U.S. Sen. David McCormick.
