My point is that Trump, et ux , are registerd to vote in Florida, not D.C., not N.Y. so they have to vote "absentee". We have used absentee voting for decades, it is approved, and it is, for the most part, safe and secure.
Voting by mail, as you and your cohorts envisage and want it implemented, is perfectly suited for those who wish to steal an election.
There is no way that all those blanket mail-out of ballots can be kept secure.
And since the vast majority of postal employees are Democrats and members of the Postal Union, they have an incentive to "lose" ballots or stall delivery of ballots.
