Look for a possible new virus to lock down America and have massive mail in fraud voting. They are already talking about virus X. The world doesn't like Trump. He puts people in their place. If not a virus, some other threat, a terroist attack again. An EMP to knock out power. Anything could happen short of killing Trump. If they kill him, they know there would be repercussions from Trump supporters they may not be able to control.
I think there have been "honest" Republicans in the past, like Reagan. He couldn't get all his agenda done for Democrats holding congress and the senate, except for a 2 year period where he got budget cuts and tax cuts passed to stimulate the economy, which it did. The deep state has been deep for a long time, especially since the 1960's.
