HARRISBURG (AP) – Counting an avalanche of mail-in votes began a third day in PA as some races from Tuesday’s primary remained too close to call. The Associated Press had not called a number of races yet where the contest was close or had a large number of votes yet to be counted, or both. The only competitive primary among the statewide races, a six-way Democrat race for state Auditor General. Democrat Michael Lamb still leads that race with the winner facing Republican Timothy De Foor in November. Voter turnout passed 1.7 million, hitting 20% of PA‘s 8.6 million registered voters. Meanwhile, deadlines to accept mail-in ballots were extended until June 9 in six counties – Allegheny, Dauphin, Delaware, Erie, Montgomery and Philadelphia.
