Scrolling through the first couple dozen posts on my following feed, I see a selfies, science educators, artists, makers, a couple naked people, a complaint about days getting shorter, and a few people talking about health conditions they've gotten under control. If you don't want to see people talking about Trump, follow people who don't talk about Trump. Or add "trump" to your list of muted words.
What you see is up to you. If you don't like what you see, there are a ton of levers in your control.
