Bring in the heavy hitters and go through the vote recount with a fine toothed comb. It should be a circus and also a target rich enviroment for fraud.
When a voter sees a registration area at a polling place and sees several voters going back to re register; something is wrong. When it is reported and the polling clowns say it’s none of our business something is wrong.
Get the heavy hitters in there and if the dem wins don’t let her in until this mess has been straightened out.
