It’s not within his powers to do so. But he could have the secret service assassinate them. Pardon the perpetrators and then assign whomever he wants the position with threats against the lives of the senate and congress as a whole for all who would vote against assigning this person. Elimate them and have the vote.
So as an individual you have 4 options:
1- vote for Biden: democrats maintain the current path as that’s literally what’s happening now
2- vote Trump: either they maintain their current path or democrats have to pivot
3- vote third party: if that party gets enough votes one of the main parties will catwr to the messaging of that party to take those voters in the next cycle as it’s an easy win
4- don’t vote: if enough people don’t vote they’ll cater more to them next cycle but that’s harder to aim in the direction you’d want to promote.
Is that a good enough breakdown? So if I were to rank my options I’d go for 3,4,2,1
