evidence: Rebecca Kleefisch, who served as Wisconsin’s lieutenant governor under Gov. Scott Walker, announced Thursday that she will seek the state’s Republican nomination for governor next year. [...] Walker, with whom Kleefisch survived a 2012 recall election triggered by the then-governor’s fight with public-employee unions, said in 2019 that Kleefisch would make a "hell of a great governor." But Walker’s blessing will not spare Kleefisch what could be a messy primary fight. [...] Kleefisch has been preparing her gubernatorial bid for months, traveling the state to meet with GOP activists and using her nonprofit organization — the 1848 Project, named for the year Wisconsin became a state — to advance conservative policy ideas. A 16-page agenda her group released last week includes broad pitches for "medical freedom" and "election reform" at a time when opposition to Covid-19 vaccine mandates and baseless claims about widespread voter fraud are energizing the Republican base.
