Three states delivered a death blow to Hillary Clinton’s 2016 bid: Pennsylvania, Wisconsin and Michigan.

Democratic misfires and Republican focus in those must-win states essentially delivered President Trump’s electoral college victory.

And some voters apparently remember that well. All three states chose Democratic governors and senators on Tuesday.

Wisconsin

State education secretary Tony Evers ousted Wisconsin governor and onetime Republican presidential candidate Scott Walker in what The Post’s Colby Itkowitz described as potentially the greatest Democratic victory in the midterms.

In the Senate race, incumbent Democrat Tammy Baldwin easily defeated GOP state senator Leah Vukmir.

Michigan

Former state Senate leader Gretchen Whitmer (D) defeated Republican Attorney General Bill Schuette in the race for governor.

Over in the Senate, Democratic incumbent Debbie Stabenow fended off Republican challenger John James, a veteran who wielded an endorsement from Trump.

Pennsylvania

Democrats in Pennsylvania easily cruised to victory on Tuesday.

The governor’s race ended in the reelection of Tom Wolf, and Senate incumbent Bob Casey was considered one of the safest bets for reelection among 10 Democratic incumbents in states where Trump won in 2016.
