Fitchburg Ald. Tony Hartmann became the city’s third resident to enter the race for the State Assembly’s 47th District. The seat is open after incumbent Robb Kahl (D-Monona) opted not to run after two terms.

Hartmann, a Democrat, joins previously announced Democratic candidates, Fitchburg Ald. Julia Arata-Fratta and Fitchburg lawyer Jimmy Anderson.

Hartmann, a longtime environmental worker and advocate, announced his candidacy May 16. He stressed in campaign materials that he wants to restore education funding, maintain lakes and develop clean-energy jobs.

The district is a stronghold for Democrats and includes much of Fitchburg, all of McFarland and Monona and parts of Cottage Grove, Madison and town of Dunn.

The primary is Aug. 9. To be on the ballot, 200 signatures from district residents had to be provided to state election officials by June 1.

One other candidate has entered the race affiliated with a party called Bernie Sanders Independent. He is Adam Dahl, 37, of Madison. Dahl, an IT specialist, told the Star that he will be on the November ballot.

No Republican candidate filed to run.
