The Brennan Center for Justice released estimates after Tuesday’s primary that show Wisconsin Club for Growth spent more than $300,000 on TV ads in support of incumbent Justice Pat Roggensack.
She won Tuesday’s primary, getting more than twice as many votes as runner up Ed Fallone, a Marquette University law professor. Third-place finisher Vince Megna was eliminated. Fallone and Roggensack face each other in the April 2 general election.
Neither Fallone nor Megna ran any TV ads in the primary.
According to The Brennan Center, Roggensack spent about $90,000 on ads before the primary.
