The Wisconsin Ethics Commission adopted a formal opinion stating lobbyists may make a campaign contribution to partisan elective state officials and candidates for partisan elective office, regardless of whether the individual is on the ballot for that election, during the contribution window.

The contribution window begins the first day authorized by law for the circulation of nomination papers as a candidate at a general election or special election and closes the day of the general or special election.

A contribution to a candidate for legislative office may only be made during the period if the Legislature has concluded its final floor period and is not in special or extraordinary session.

The contribution window opened on May 14 and will close on November 3.
