Mark Brentley Sr., a veteran Pittsburgh school board member, is challenging state Rep. Jake Wheatley, D-Hill District.
Mr. Brentley is in his fourth term on the elected school board. He has run for the legislative seat three times previously, losing in the Democratic primary in 1994 and 1998. Running as an independent, he lost the 1996 general election.
Mr. Wheatley is in his third term in the House, representing the central Pittsburgh district that includes the Hill District, parts of Oakland, the North Side, the South Side and Hazelwood. He ran in the Democratic primary for mayor last year, coming in third behind Mayor Bill Peduto and former state Auditor General Jack Wagner.
Mr. Brentley is seeking the Democratic Party endorsement for the nomination. He said he had not made up his mind on whether he would continue his candidacy if he did not prevail in the party vote next month. He also said that if he won the legislative seat, he would resign from the school board.
