Swiss Population Cap Vote Defies Confident Polling Predictions

Swiss voters decide June 14 on a constitutional population ceiling of 10 million. Pre-vote polls show rejection likely. Yet the 2014 mass immigration initiative passed despite trailing in surveys, triggering a decade of unresolved legal and diplomatic friction. Migration referendums consistently surprise: undecided voters break sharply against binding constitutional language at the ballot booth. A passage would immediately trigger diplomatic tension with Brussels over Switzerland's free movement agreement.
