Curious about Nixon

This was a tad before my time, but when Nixon resigned, the vast majority of the USA agreed with that decision and felt that Nixon had done something seriously wrong. Am I correct? Were there many folks in subsequent years who felt Nixon had been wronged? But we all knew Nixon was involved in the break-in.

I remember when Clinton was impeached my dad telling me he thought Clinton should resign. In my mind being untruthful about an extramarital affair is much different than orchestrating a political break-in. As I remember afterwards, most Democrats and some Republicans felt the affair was minor. The republicans who thought this was a major offense had issues with Clinton before that. But we all knew that Clinton had an affair and it looked bad upon him and the office of the president.

But I don't understand Trump. It's like his supporters are in complete denial. Sure there are some who think Trump is a scoundrel and still support him, but it seems like most completely deny that he did anything wrong. I simply don't see how anyone in a right mind would think Trump did nothing wrong or did nothing that made him look bad or disgraced the office of the presidency. With Nixon and Clinton, I think most of the country agreed they did something wrong. The difference was that whether one felt the action justified removal from office. Frankly, I am shocked that 75-80% of the USA can't agree that Trump is a slimy, crooked man. I wouldn't have so much of an issue if his supporters admitted to that and still supported him in spite of that. But they don't. Instead they live in a completely different reality. And it's not just 20% of the country - it's probably 35-40%. If we can't agree on basic reality, we are doomed.
