(Pittsburgh, Pa.) If you want register to vote with a mail-in ballot for the May 18 primary, you must do so by 5 PM tomorrow.

Acting Secretary of State Veronica W. Degraffenreid urged voters who are voting by mail to submit their application as soon as possible, to allow sufficient time for their ballot to be mailed to them and then returned to the county by 8 p.m. May 18, Election Day.

“Pennsylvanians still have time to apply online for a mail ballot or to apply in person at their county election office,” Secretary Degraffenreid said. “They can also vote early in person by applying for a mail ballot at their county election office, filling it out and returning it all in the same visit until 5 p.m. May 11.”

So far, more than 706,900 Pennsylvania voters have applied for a mail-in ballot and more than 47,000 voters have applied for an absentee ballot.
