Like most Rockefeller & Gates sponsored rags, factcheck.org's post is muddying the waters with opinion, circular & contradictory reasoning, & deceptive headlines. This piece you sent me were mainly partisan opinions of the same people who advocate for mail in ballots, masquerading as some voice of authority that the audience is supposed to obey by fiat. There was no discussion, other than a sentence of an opinion, about the process.

Unlike the article above I posted, there are no links to source documents of procedures or any source data other than partisan opinions.

Dude. This isn't complicated. We call them mail-in ballots and absentee ballots, interchangeably. Absentee is an older term and may be falling out of use.
