In Florida, a Republican governor closely aligned with Trump has come under scrutiny for being slow to close the state. In Wisconsin, the Democratic victor in last week’s Supreme Court race captured 28 counties, up from the 12 that Hillary Clinton won four years ago. In Michigan, a Democratic governor has seen her approval rating rise against the backdrop of a fight with Trump.
