1976 Wisconsin Senate Election (Halley Series)

The 1976 Wisconsin Senate Election took place on November 2, 1976, congruent with the 1976 House Elections and the 1976 United States Presidential Election.

Incumbent Vice President Bryson Halley decided not to run with President Connolly for a second term. Connolly went on to lose the election in a hotly contested congressional tie-breaker.

Halley defeated Republican Wisconsin State Senator Mark Harlan by a large margin for a senate race in Wisconsin at that time.

Halley became the first Democrat to represent Wisconsin in the U.S Senate in 16 years.

Halley would later change his party affiliation in 1980, after the Democratic Party nominated former Republican Richard Nixon for President.
