Being a hardcore Trump supporter has some similarities with being in a cult. One way to figure out how to deal with your loved ones who are hardcore Trump supporters is to look at the advice for handling a situation where a family member is in a cult (google some articles).
In many cases, people fall into cults who are fairly normal people, fairly intelligent in many ways, and not bad people. You can disown them, but you can also try to help. However it´s likely going to take a significant amount of time, stress and energy and even money and you may still fail. I don´t think you likely get very far in a short time.
Here are some ideas. This is mostly just based on googling a few articles from experts with experience dealing with people in cults rather than my own ideas. Some of it I adapted. I don´t have any experience of knowing anyone who was a Trump supporter or has been in a cult.
--Don´t have angry discussions with them. Speak to them politely and if it gets angry, circle back later.
--Meet them on an equal footing. Be respectful. For example accept one of their arguments, agree with one of Trump´s policies, and disagree with one liberal policy.
--Separate them from their source of info for a while. For some, this means getting them away from Fox News or some other TV network, for others you might challenge them to take a break from social media or their phone for a few days (make it a challenge you both do, and don´t say why you are doing it), for others it might mean getting them to stop going and physically meeting up with some group. Use sneaky tactics to achieve this, for example going away on holiday together to a foreign country where there is no Fox News and booking a hotel with no wifi (is that still a thing?) or phone signal...or calling them or inviting them to do something with you at the same time that Sean Hannity or Tucker Carlson or whoever else you know is brainwashing them is on....this one may have to wait until summer given the vaccine.
--Talk to them about other issues first to make a bond (for example shared childhood memories) and then from there go gently into politics. A good place to do this is on a walk in nature, like in the forest (ideally somewhere where you know there is poor phone signal so they don´t get news), which is something you can do now. In an absolutely ideal world, going to somewhere you had shared childhood experiences, years ago, before falling into the cult, is even better.
--Ask them which of Trump´s policies has benefited them personally and how. This one is meant to have them think and realize that Trump did nothing for them personally. However, there is a risk that it could backfire.
--Talk to them about how their are so many lies on facebook/parler or whatever they are on but do it in a non-partisan way, citing clear examples from both sides of the political spectrum. If they say the mainstream media is biased against Trump, agree with this. It obviously is and you will lose credibility if you try to deny the obvious. But point out that the mainstream media doesn´t tell outright lies like you can on facebook.
--Team up with someone else for the effort so you tag team the person. Be loving rather than hating.
You have to adapt these ideas to your situation, for example the ways you separate people from their kool aid will not likely be exactly the same as my suggestions, but use them to get your own idea.
Don´t place too much faith in these ideas because I don´t have experience and haven´t thought about it this much.
If you yourself are in a difficult place - depressed, angry, medical issues, loved one died recently etc it might be better not to engage at all on the political issues. Just tell them you don´t want to talk about politics for a while and you want to build the other aspects of the relationship and take a break from politics, but you are happy to talk to them about it later.
