You cannot reason with the Bros. They are as bad as the Trumpers. They really believe that Bernie would have won if he were nominated and nothing you say can persuade them otherwise; they also believe that Hillary was as bad as Donald so there would be no benefit supporting her. They should be ignored and the focus should be on those who voted for Trump out of desperation because their lives had deteriorated under both Bush and Obama. We also need to work to reverse the Republican voter disenfranchisement laws that contributed to the decline in minority votes.
