I believe you have to now look beyond Wisconsin. You’ve got 2 governors races in 25 in competive states. There will be others.
Governor races are an oddity sometimes. Manchin was popular in a red state that stayed red. Beshear is popular in a red state that stayed red. Florida toyed with being purple; at the district level it was majority red but it had a blue Supreme Court in 2000 and came close to electing a Democrat governor in 2018 (who was later discovered to be a gay meth addict).
Even Wisconsin has been swinging back and forth: Scott Walker won two terms after the teachers unions stormed the state house. And Glenn Youngkin won in Virginia after Terry McAuliffe told parents they had no business interfering in their children's schooling.
Governor races as portents of the future are more like turning a cargo ship at sea -- it takes a long time for the results to trickled down as change within the state. California was effectively red from Ronald Reagan to Pete Wilson, but then turned blue during the Clinton administration.
