Swiss voters headed into a nationwide ballot day with four major issues on the table, including a contested plan to expand the national motorway network and three other federal proposals that had all become more polarised during the campaign.
The clearest shift in the run-up to the vote was on the motorway question. A second poll by gfs.bern, cited by Swiss Info, found that a small majority of voters, 51%, were opposed to the expansion project while 47% backed it. Just 2% were undecided. That marked a reversal from an earlier survey a month before, when supporters still held a narrow lead.
The motorway proposal aimed to relieve congestion on parts of the network, but the polling suggested the campaign had turned against it. Swiss Info said supporters of the plan were losing ground and that the issue had become the most sharply settled of the four votes. It also reported a widening divide by gender, with a majority of women leaning against the plan and a majority of men leaning in favour.
The same poll suggested that health-care financing reform was still on track to pass, but with a slimmer cushion than before. Support for the standardised financing model, known as EFAS, stood at 54%, with 37% opposed and 9% undecided. The evidence package says the proposal was backed by parliament and the government, but that trade-union arguments had gained traction and could still affect the final count among undecided voters.
Two tenancy-law amendments also appeared to be losing support. One proposal sought to tighten conditions for subletting, while the other would have made it easier for landlords to terminate a lease if they wanted to use the property themselves. Swiss Info's polling summary said backing for both had fallen and that the no camp had gained ground across the campaign. Even so, the subletting reform still held a narrow lead in the survey, while the owner-occupation termination proposal was already facing clear rejection.
The broader political takeaway in the source was not just that voters were drifting toward no on multiple questions, but that trust in the authorities appeared to be eroding. gfs.bern researchers told Swiss Info that the pattern was unusual for initiatives promoted by the government and parliament. Their view was that the electorate's confidence in authorities had dropped to its lowest level since 2018.
The packet therefore points to a ballot day defined less by a single landslide than by a series of closely watched tests of public confidence. Each issue had its own policy logic, but all four had become exercises in whether Swiss voters were willing to endorse the federal government's judgment. The polling showed the motorway plan most vulnerable, health reform still competitive, and the tenancy measures under growing pressure from the no side.
