Trump knows he will lose in the 2020 election unless he uses extreme measures to "suppress the vote". Wisconsin Republicans tested this strategy by forcing people to vote in person in the middle of a pandemic. And "Moscow" Mitch was willing to risk the lives of Senators just to fulfill his own agenda. Trump believes the only good voter is a soulless lifeless one in need of brains.
Trump is popular with uneducated zombies in a state of extreme decay.
