They’re putting the notion of assassinating the president out there into the weak minds of their listeners, who will take that information and do with it what they will.
I do understand they can do multiple things at once even if they can barely walk and chew gum, and I would like if they were wiped from the face of the earth, but I would much rather that they turn their attention towards the president, instead of putting their attention on trans people or whatever racial minority comes up week by week to rile up the base. The president has a large amount of protection on him at all times, the chances that any right wing nutjob can target him effectively strike me as shockingly low, and if they did target him, then probably you’d see something actually happen to prosecute them. Basically nobody else has that same level of protection.
