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% less
than the percent the President won on election day. If Trump won a county
by 80% of the vote on Election Day, he won 40% of the mail-in vote for a county.
If the President won 60% of the vote on Election Day, he won 20% 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% of the vote on Election Day.
