Enough for what? Switzerland doesn’t really have coalitions, that’s more Germany. At most there’s “coalitions” on single issue votes. And there’s 7 presidents, proportional to parties, so no such thing as a ruling party or coalition. That said, the FDP votes identical with the SVP in nearly everything already, especially economic issues, so much so that’d it’d be hard to distinguish them based on votes, minus the blatant populism.
