I think the libs are doing this because they’re trying to convince the chuds that Trump is a criminal and that they shouldn’t support him. It will never work because Biden is also definitely a criminal; the entire american government is criminal. The libs are also worried about Trump winning in 2024 (even though Biden and the Democrats are the greatest and most progressive team in the history of the universe and definitely cannot fail; only WE can fail THEM).
“I don’t know how ole donnie will wriggle out of this one!” but imprisoning presidents is a regular thing outside of the USA so I’m not sure why it couldn’t happen here. Chuds will respond with stochastic terrorism and suicide-by-cop at the very least.
