I think one can tell a lot from whether an app or social media allows one to download pictures or videos.
This is easy on Mastodon and Nostr, less so on Bluesky and Farcaster.
There was an interview with a white farmer woman in a swing state on Dutch television two days ago and her argument for voting Trump was "the US needs a strong leader".
Two things:
1) If you ever utter "strong leader" in relation to upcoming elections, your voting rights should be taken away immediately.
2) You want a strong leader and choose Trump... what?! The man is a bully and everything what a good leader should not be.
