The Gateway Pundit provides proof of mail-in ballot fraud in Pennsylvania:
In almost every county throughout the state, the President was awarded a percent of votes 40{3aedcb51dac2fbb83a885d32b07950f3050377138d02430f831f0a3ede84357a} less than the percent the President won on election day. If Trump won a county by 80{3aedcb51dac2fbb83a885d32b07950f3050377138d02430f831f0a3ede84357a} of the vote on Election Day, he won 40{3aedcb51dac2fbb83a885d32b07950f3050377138d02430f831f0a3ede84357a} of the mail-in vote for a county. If the President won 60{3aedcb51dac2fbb83a885d32b07950f3050377138d02430f831f0a3ede84357a} of the vote on Election Day, he won 20{3aedcb51dac2fbb83a885d32b07950f3050377138d02430f831f0a3ede84357a} of the mail-in vote in another county. This pattern occurred in almost every county with the only noticeable exception of Philadelphia, where the President only earned 30{3aedcb51dac2fbb83a885d32b07950f3050377138d02430f831f0a3ede84357a} of the vote on Election Day.
