evidence: Rebecca Kleefisch, Former Lt. Gov. Under Scott Walker, Launches Gubernatorial Campaign MADISON, Wis. (AP) — Republican Rebecca Kleefisch, who spent eight years as lieutenant governor under Scott Walker, launched her campaign for Wisconsin governor on Thursday, casting herself as someone who will "fight for you" while deriding the Democratic incumbent as a weak failure. [...] Kleefisch, 46, is trying to become the first female governor in Wisconsin history. She is the best-known Republican to officially get into the race against Evers, who is seeking a second term in 2022. State Rep. John Macco, of Green Bay, longtime lobbyist Bill McCoshen and 2018 U.S. Senate candidate Kevin Nicholson, a former Marine, are also considering runs for governor as Republicans.
