Caleb Frostman handed Wisconsin Democrats a major victory in Tuesday night's special state Senate election, flipping a solid red seat in a district President Trump won by double digits in 2016.
Why it matters: This is the 44th Republican state legislative seat Democrats have flipped since President Trump took office, according to the Democratic Legislative Campaign Committee.
The bigger picture: While Republicans held onto another vacant seat in the Wisconsin legislature's lower chamber, Democrats managed a repeat of the January special election when they flipped a district that had long been held by Republicans since 2000 and won by Trump.
The backdrop: This comes after the National Democratic Redistricting Committee, a group led by former Attorney General Eric Holder, successfully sued Walker, who refused to call a special election to fill two legislative seats vacated by Republicans who joined his administration last December.
