Tell them that no matter who wins the Primary, the DNC will mandate that he/she/it will HAVE to run with Peeder Buttplug as VP.
Then ask how they will like all their heroes AFTER they assassinate the elected president, just so they can end up with (((their))) choice of Marxist Peeder Buttplug as president.
They will all flip after that happens.
Unfortunately for us all , it would be to late then.
