@b_jonas There's currently 9 ongoing elections (MO, PPCG,
Engineering,
Hardware Recommendations,
Bioinformatics,
Bioacoustics,
Cardano,
Politics,
Open Data). That's not too unusual: there's usually elections on a bunch of different sites, except during SE staff holiday periods like Christmas and New Year. Maybe you're just noticing now because some of them are sites that you're familiar with.
