Sort of funny, it's often the unhinged diehards that are willing to break ranks to get proactive, so leave it to them to take the threat of Trump going to prison seriously. That said mainstream GOP also probably have plans, they're smart enough to stay very quiet though.
The better ideal, to me, is that an even dumber, louder, more racist bigoted piece of shit comes along to take the banner from Agolf Twitler and is hammered like Your Mom on polling day
(Nothing against Your Mom personally, but I had a Your Mom joke already jacked into the chamber & it had to fire)
This sort of planning only makes sense if he is unable to attend the convention by way of incarceration. Which I guess is a live enough possibility they have to plan for it
