It may be unpopular but Volt is increasing its presence on all levels from local councils to European Parliament, so there’s a desire among some voters for more EU federalism. In Germany they may come close to the results of FDP on the upcoming elections.
Fortunately in my country of Austria the liberal party (NEOS from the EU Renew Europe faction) already supports a "United States of Europe", but it "only" has around ~10% at the moment (though it is growing).
But the new government of pro-russian neonazis (FPÖ) and conservatives (ÖVP) will probably be very anti-EU.
