When did Wisconsin establish special elections to fill a vacancy for United States Senator from Wisconsin?
AChapter 647, Laws of 1957, provided for a temporary appointment by the governor, and the appointee would serve as U.S. Senator until a regular primary and general election cycle, either the next September primary and November general election if the vacancy occurred before 60 days prior to the second Tuesday in July of an even-numbered year, or the primary and general election two years hence if the vacancy occurred after that deadline. (If the next general election would have ordinarily been for the full six-year term anyway, the appointed Senator would simply complete the unexpired term.) 1985 Wisconsin Act 304 established the possibility of a special election to fill a U.S. Senate vacancy, completely eliminating the interim appointment by the governor, leaving the seat empty until after an election. Current law provides that a vacancy that occurs between the second Tuesday in May and the second Tuesday in July in an even-numbered year will be filled at the regular September primary
