HARRISBURG, Pa. (AP) — Voting has begun in the presidential battleground state of Pennsylvania. Counties are mailing out ballots, offering over-the-counter voting and opening satellite election offices. Seth Bluestein sits on Philadelphia’s election commission. He said Wednesday that voters in the state’s largest city have returned about 15,000 mail-in ballots. That’s about 10% of the 150,000 ballots the city mailed so far. It’s also opening 10 satellite election offices. Allegheny County, home to Pittsburgh, says voters who applied for mail-in ballots have started receiving them. Montgomery County, the state’s third-most populous county, is mailing out ballots and this week it’s unveiling eight satellite election offices and a mobile voter services van. (Photo: AP)
