Pennsylvania has published the letter from the Postal Service. In the United States, where elections are held on working days, there is an opportunity to send ballots by post Due to the Corona crisis this year, many voters are expected to take that opportunity.

A recent poll found that three-quarters of Republicans physically and 50 percent of Democrats want to vote by mail-in. Democrats have demanded a mail-in vote, but Trump has opposed it from the beginning. In such a situation, the postal service itself has warned about postal voting.
