I think for some people, Trump gives them a green light to be their worst selves and to them, it feels good. It makes them feel better to insult, humiliate, hate other people. Trump doesn't act the way most politicians do - he swears, he criticizes, he mocks, etc which manipulates people into believing he's 'just telling it like it is'. Every so often though, there is a slip to show it's a facade like "I love the poorly educated". And like any other predator, the most vulnerable are at biggest risk of being victimized, scammed and exploited. And it's sold as patriotism! He hates America, imo, because America doesn't show him due deference. He has always, even while hugging a flag, talked America down. It's actually rather perverse in my opinion.
But for other people, I don't think it's so much how Trump makes them feel as much as what Trump can do for their own thirst of ambition - for their bank accounts, notoriety, careers, elections, etc. Being tangetially related to Trump, clinging to his coattails, has made the right people an awful lot of money, influence and power. It was CBS CEO Les Moonves who stated in 2016 that Trump was good for ratings.
Ultimately, I think Trump offers something to everyone who supports him and for some people, it will simply be the offering of a community of like minded people - a feeling of acceptance.
But imagine how good America's enemies feel watching talk of civil war? When Americans are fighting each other instead of autocracy across the world? Autocracy is really at the core of the DC and Georgia cases - one man wanted unfettered power to overrule democracy itself because if he couldn't win power legitimately, he'd do anything he could to steal it.
