HARRISBURG — Pennsylvania counties have processed about 283,000 absentee and mail-in ballots for the June primary, and requests from Democrats are three times more common than from Republicans, state elections officials said Tuesday.

The Department of State said 89,000 absentee ballot requests have already been processed. During the 2016 primary, 84,000 votes were cast under the absentee ballot system, which is available only to those who offer an acceptable reason they would not be able to vote in person.

Counties have already processed 195,000 requests for mail-in ballots under a state law passed last fall that permits them for any voter who requests one. Pennsylvania has about 4.1 million registered Democrats and 3.3 million Republicans. Of the absentee and mail-in requests for the primary processed so far, about 209,000 are from Democrats and 73,000 from Republicans.
