You have two potential candidates who are chomping at the bit to start killing people en masse
And about a third of your party are eager to see them do so.
If 20% of Dems are as ill-informed as 30% of Republicans, that's a sad story but I guess it help explains FOX News ratings. Still, unless those Dems jump ship and do something truly stupid, they won't be responsible for putting one of your warmongering lunatics in the White House.
PS. I suppose you think the question Trump flubbed regarding the nuclear triad was also a "question meant to trick people." Clearly he'd never heard the term before, and he wants to be President of the United States.
