And that happened even after they arrested him and tried to put him in jail. What's happening now might be shocking but not unexpected at all.
They really didn't. It was a dog and pony show under the belief that he would not make his way back into power. The dems/reps did not want to set a precedent of holding a president to account for doing terribly illegal things. They didn't intend to actually do anything to prevent this.
And so here we are.
If so, they have been well-paid for that bit of "strategy". Trump was able to delay the cases long enough that the election came first, and now he has immunity at least while in office.
I think they didn't realize the moment the country was in. They put a judge in charge of the justice department when we needed a bull-dog prosecutor. It was a bad choice.
