The SVP would be the leading party at 29.9 percent, two points above its 2023 result and just under the 30.4 percent it reached in the October 2025 barometer.
At 13.3 percent, the FDP would post its worst national election result in its history, though it would still edge ahead of the Centre at 12.6 percent.
The Centre falls 1.5 points from 2023 to 12.6 percent. Together, the FDP and the Centre reach 26 percent, four points less than the SVP alone.
Health insurance premiums and climate change rank as the most urgent issues, and over 80 percent of respondents say the government is too friendly toward Washington.
The Swiss People's Party (SVP) would be the clear winner if the vote were held today, with 29.9 percent of voting intentions. That is two points above its 2023 result and would beat the party's previous best of 29.4 percent, recorded in 2015. The SVP had reached 30.4 percent in the October 2025 barometer, so the latest figure sits just below that earlier peak. The Social Democrats (SP) stand at 19.3 percent, one point above 2023, which Sotomo says would be their best result since 2007. The Greens reach 10.3 percent, up 0.5 points on 2023, while the Green Liberals (GLP) are at 7.1 percent, 0.5 points below 2023. The Evangelical People's Party (EVP) is at 2 percent.

The Centre would drop 1.5 points from 2023 to 12.6 percent, the largest loss of any party in the barometer. The figure is also one point below its result in the 2025 barometer. The Radical-Liberal Party (FDP) would lose one point from 2023 to 13.3 percent, which the study presents as its weakest result in its history at national elections. Even so, the FDP would move ahead of the Centre and into third place. Taken together, the FDP and the Centre reach 26 percent, four points less than the SVP alone.

Gender splits are visible in the barometer. Among men the SVP reaches 34 percent, against 26 percent among women, while the SP is backed by 23 percent of women and 15 percent of men. The Greens draw 12 percent of women and 8 percent of men, and the FDP is stronger among men at 16 percent against 11 percent of women. By age, the SP is at 25 percent among voters aged 18 to 34, second only to the SVP at 27 percent, and it falls to 19 percent among those over 65. The FDP is strongest in the oldest group at 16 percent, yet it still trails both the SP and the SVP there.
Respondents rated health insurance premiums and climate change as the most urgent challenges. Concern about premiums appears across party lines, while the urgency of climate change varies with party affiliation. On foreign policy, over 80 percent of respondents think the government is too friendly toward Washington. Almost three quarters consider Switzerland's official stance toward Israel too friendly. The survey finds that shifts in party support only partly reflect the population's main concerns.
Economics Minister Guy Parmelin gained ground over the past year. Forty-two percent of respondents now describe him as one of the most influential members of the Federal Council, up from 17 percent in the earlier survey.
