Definitely, and if all voting is done by mail-in, there is no check-in at polling places, no in-person verification of identity and no way to double-check the number of people who voted. If it's all via mail-in, any crooked election supervisor can simply discard a number of ballots, and it would be extremely difficult to determine that all votes were actually counted. Further, a typical election supervisor would have a pretty good idea which ballots were for which party, based on which area of the precinct the ballots came from, or by filtering out ballots based on names (Jewish, Hispanic, African-American, etc.). The chance of fraud is multiplied big-time.That's right. Easy to tell which ones they count and which to "lose".
