Pennsylvania has rejected nearly 375,000 mail-in ballot applications so far

Pennsylvania has rejected hundreds of thousands of mail-in ballot applications this election year, with the vast majority of those rejections occurring because of duplicate ballot requests from voters in the state.

The state "has rejected 372,000 requests for mail-in ballots," with "more than 90% of those applications, or about 336,000," occurring due to duplicate requests, ProPublica reported this week.
