Special interest groups spent more than $3 million as of Monday morning in the Wisconsin Supreme Court race.
Groups supporting Dane County Circuit Judge Jill Karofsky have spent nearly $1.9 million. Groups backing incumbent Justice Dan Kelly have spent nearly $1.2 million. The election is next Tuesday, April 7.
Until late last week, groups backing Karofsky had a large spending advantage over groups that were supporting Kelly, but two outfits that support GOP and conservative candidates filed more than $1 million in new spending to support Kelly to close the gap.
Karofsky has backing from Democratic contributors and outside groups and Kelly has support from GOP contributors and groups.
