Too many people in both chambers owe him their livelihood. Some in the Senate may be brave enough, since the next tranche is Democrat-heavy, and those up for election in 2020 may want someone else that the top of the ticket. But there are a whole bunch elected last year who will be up in 2022 who wouldn't be there were it not for him. If they're going to move against him it'll be sooner rather than later so that people have time to forget, assuming a barrage of 3am tweets doesn't sear their betrayal permanently into their voters' consciousness.
Before it gets to the Senate, it needs to pass the House, and there are anything up to 40 there who owe him their seats, and they're all up for election every two years anyway.
The whole party knows they're beholden to him, and he knows it. He even made party chair Reince Priebus his bitch. It will take an astonishing act of bravery for enough to back the motion, and Paul Ryan would have to let it come to the floor. It's also worth remembering that both sides will be well aware that if Trump is ousted, then the job falls to Mike Pence.
