I read somewhere that you are having concerns about getting your ballot. Perhaps this would explain the delay. I'm assuming you voted in the Primaries.
Pennsylvania has rejected nearly 375,000 mail-in ballot applications so far
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.
According to ProPublica, the significant number of duplicate applications came about largely due to voters having requested a general election ballot during the state's primary election as well as closer to the general election itself.
The mass rejection "is unlikely to have a big effect on turnout," the organization said, as those whose applications were rejected will likely receive one eventually. Those who do not can still vote in-person on Election Day.
