● WI-01: Peter Barca, a Democrat with a long history in Wisconsin politics, announced Thursday that he would challenge Republican Rep. Bryan Steil for the state's 1st District, a constituency that's descended from the one Barca briefly represented three decades ago. While Republicans have held it ever since, Barca's entry could put into play a seat that the GOP has rarely had to sweat.

Barca, who stepped down last month as state revenue secretary, is the first major contender to enter the Aug. 13 Democratic primary, and it's possible he could be the last. Right after his launch, former Assembly Speaker Mike Sheridan informed the Milwaukee Journal Sentinel's Lawrence Andrea that he'd decided to back Barca rather than run himself.
