He wanted to make his country great again.
Do you know why he wanted to make his country great again?
In my opinion, Trump realized that his country is declining. I don't know the exact reasons.
If he wants to continue the status quo then that doesn't make the country better. He didn't change the country anyway.
Maybe he just didn't have enough time to change it. He shouldn't have had to face those impeachment hearings, that's for sure.
The hearings were just there to decide if he had done wrong, which in many people's eyes he did. The hearings were legitimate and a way to keep power in check. Holding people accountable for their actions is important.
