David, Thats the easiest question to answer from a MAGA Republican.
First he did everything he could think of too overturn a fair and honest election. This included threatening, bullying and bribing Republican state election officials.
Secondly, he managed, led and approved of the Jan. sixth insurrection according to Republican witnesses that testified before the Jan sixth committee.
He ignored constitutional limits to presidential power. He knowingly used his high office to make money. Not building a much needed new FBI building because he feared that the sight of the new headquarters of that federal agency would mean getting rid of the old FBI sight which would be bought by a competitive hotel company to compete with Trumps Washington sight. These are the most obvious answer to your question, but I am looking forward to his trial.

Every single one of his rallies are like that. Wherever he goes people are cheerful, up and happy to be there. The only negativity comes from opposition protestors. It is so clear that Trump loves America and the people who live here, and that he cared enough about us to make our lives better, or he tried to while going through the worst attack on his person consistently throughout the seven years he has been on the political bandwagon.

When people say he incited a riot, it goes against everything he has ever said to those of us who follow him and what he has to say. If the left could just sit down and listen to him - not "how" he talks, but what he is actually saying - they might see what we see.....what we SAW when he was in charge of our country. He does NOT want riots and hate. He wants to see us happy and satisfied with the way our lives are going. And he succeeded. Not for very long, but the fact remains that he is capable of doing great things for us. That is what Democrats don't want to see. They don't want to admit that Trump knows what to do to make us, the peons of America, happy. Doing that for us takes money out of their pockets, and God help anyone who tries to do THAT to them!
