bob, it's a tough position. Of my entire family (mother and father's side) the only ones I wouldn't put money on having voted for Trump are my two younger sisters (one's a confirmed liberal, the other rarely mentions politics). For the most part, I don't talk about politics. Perhaps I should change that. Certainly don't listen to those saying "ah, politics doens't really matter enough to talk to your family about."

Blew the whistle on a company his grandad was on the Board of. WOuld you respect him more or less if he said "hey, it's not worth opening a family rift"?
There's been some good advice and some terrible advice ITT. Avoid making declarative statements like "Trump is a fascist!". Avoid making any at all. Focus on a lot of Why and How questions, like "How do you expect Trump to bring back those jobs he promised?" and "why do you think he's been sued so many times?" Those questions have to be posed in a sympathetic neutral tone, not a "gotcha one". If they respond with some insane conspiracy say something like "oh really? I never heard that. Where did you learn that?". The goal is for them to start actually looking for info, and if you can push them to do so outside of their lunatic bubble so much the better.
If they are getting agitated say something like "you probably think I'm a terrible son for arguing about politics with you" to which (unless they're actually soulless) "of course not, I'm proud that you're so smart and well-read" (and once they've said it, subconsciously they'll start to believe it, helping prevent them from blaming you for talking about politics).
I absolutely disagree with suzzer's idea of blackmailing them with your presence.
