They don’t need to vote 20% Republican. They just don’t have to turnout like they are voting for the first black President. Biden isn’t popular with them either and we should pretend that he’s able to drive turnout in substantially greater numbers than Obama at the height of hope and change?
That’s the point of mail-in voting.
They WILL all be registered to vote. They WILL get their mail-in ballot.
And they WILL hand the ballot over to their designated Democrat ballot harvester to fill in for them, and submit, or there WILL be hell to pay.
