All 46 members of the Council of States were elected from all cantons of Switzerland.

These gains – the first time minor parties had won representation in the Council of States since 1995 – came at the expense of the Free Democratic Party, which lost two seats, and the Swiss People's Party, which lost its seat in its stronghold of Zurich to the GLP.

[1] The second round saw a number of notable races, for instance the election for the second seat in Zürich, where SP candidate Chantal Galladé agreed to withdraw and support GLP candidate Verena Diener against SVP candidate Ueli Maurer, increasing the centre-left's changes in the second round.

[3] Four candidates contested the election for the two seats in Tessin -- Dick Marty (FDP, over 40,000 votes in the first round), Filippo Lombardi (CVP), Franco Cavalli (SP) -- both of whom had over 30,000 votes—and finally Attilio Bignasca (Lega).

The second seat for Lucerne was handed to CVP candidate Konrad Graber in so-called "silent election" when no other candidate filed to run against him in the second round.
