They're every bit as retarded as the people who thought Trump being impeached would mean Hilary becomes pres. If Biden is impeached (not jailed, which he can't be, Trump also argued that he can't be jailed for crimes that may have been committed as President but he totally didn't commit any crimes guys), then Harris becomes Prez. If she's impeached, Pelosi becomes Prez. If Pelosi is impeached, then Anthony Blinken becomes Prez. If he's impeached... look, the point is, there is absolutely no impeachment line of succession for Trump to become Prez.
The only way it can happen is if he is elected to the House and becomes speaker, which is something a lot of Republicans are encouraging him to do.... except that still won't work since there's almost no chance the Republicans will have enough seats in the Senate to remove Biden, nevermind the fact that even if they did have 60+ seats in the senate, it is extremely unlikely they'll have enough votes to remove Biden.
You'd think intelligent, Constitution-loving patriots would know this. But we're not talking about Constitution-loving patriots. We're talking about retards who love a fat retarded conman.
