Mail-In ballots are a highly unreliable way of voting and cannot be verified.
No foreign country uses Mail-In ballots
Note, Mail in ballots are not the same as Absentee Ballots.
RED CITIES CAN PLAY THE MAIL-IN GAME
If there is no voting integrity, Red Cities can also play the Mail-In ballot game, correct?
In fact, why not let Red Cities keep counting votes just like Blue Cities, even Today after the election, correct?
NOTE; Blue Cities are extremely corrupt. Just look at their mayors and their many decades long of population decline.
All Blue Cities have extremely corrupt political machines throughout all of their city departments and salaried and contract positions; hence, you can count on their entire voting apparatus to be very corrupt.
