IMO, they are set up much more firmly to catch invalid ballot casting operations this year, already have a few investigations going on because of it.. When most Repubs voted day of, it was too late to look into anything and they kept ignoring any inquires. This year, republicans are showing strong form the get go and, there will still be those people who vote on election day itself still to go. I would feel free to vote any time (that your state allows or is set up for). Some states have Early voting dates specific, a couple states like WA, is still all mail in and no walk in to vote (Ick). All depends on your state but, yes, go ahead and vote early(as in not the day of) if that is what your state does. They have been working around the bulk of Repubs on day OF so, set up the counter to that well in advanced depending on how much ahead they were after early vote.. Enough republicans vote early, they wont have a solid plan for Election day shenanigans. Remember that, many people went in to vote on Election day only to be told that they already voted? Yeah, that kinda BS.
