> But the sentiment of nuclear depends purely on which party you vote for, I don't think the language itself has an impact.

People aren't really partisan like that in Switzerland. They'll happily elect people from one party then vote against the party on specific issues in referendums or initiatives.

For something like nuclear, people who vote for green party might be mostly aligned with the party because it's a key issue for them while people who vote for center or right parties won't really care what the party recommends.
