How to have discussions with republican family about the recent developments?

Hello! I'm sure this isn't the first time something like this has been asked, but I'm pretty desperate. I'm hopeful I have a better chance of educating my family, as they're not as staunchly and violently MAGA as some- but my father especially grew up in Red Texas, and has family who is MAGA. He's smart, but equally falls completely for all of Trumps and Elons lies. He believes Elons takeover of the treasury is fine because "hes fiscal conservative and believes Elon will cut all of the useless spending".
I believe his main problem is being completely unwilling to admit when he is wrong. I do not believe he has ever admitted he was with anything- a pride thing, sure, but my mother- newly left- leans central and will never put a foot down when confronting him about his beliefs. (I'm a 'democrat' 20 y/o female, so I'm sure that doesn't mean nothing in regards to how little I'm taken seriously.) We talked to him about tariffs, and when he faltered and was unable to justify them, simply changed the subject, and everyone let him (I am guilty of this as well.)

All that to say- is there some source, some news cite, some talking points that can convince him whats happening is very bad? How its bad? What all exactly is happening? I love my family very much, and I want to do the best I can to help educate everyone I can on the political events happening right now, It feels like I am talking to a wall, and I feel morally obligated to not give up on the people in my life, and let misinformation or centrist apologetic bullshit blind people. I'm unable to attend protests, and this is the one small act of protest I'm able to do, but I need advice, If possible.

I apologize if this was convoluted (or not allowed), I'm admittedly exhausted from the stress of the last few days, and I feel almost insane being told to "stop paying attention to politics" or that things "aren't that bad". I want to do something. I really want to believe in the power of the people.
