ⓘ What do the party and ideology labels mean?
On the ballot, partisan candidates run under a party — in Wisconsin almost always Democratic or Republican, with the occasional third-party or independent candidate. Words like progressive, conservative, libertarian, or democratic socialist are labels people use to describe themselves, not separate parties on the ballot. A label is a starting point; each candidate's sourced positions show where they actually stand.
