Democratic candidates benefit from large amounts of people voting, so by making it easy to vote with mail in ballots sealed the deal for Biden. Yet another way the pandemic caused Trump to lose.
And Republicans benefit from the level of I.D. they demanded this election in order to vote.
Before you cry foul and say but these illegals shouldn't vote I'm talking about the POOR who typically will be the ones without drivers licences (no car(, passports (no foreign holidays) , no rent card or any number of other documents that comfortable people take for granted. Also the young are less likely to have these documents to hand and they again typically are within the Democrat demographic.
