Yesterday in an article in The Nation, John Nichols made an excellent point about the significance of the 2018 Blue Wave to Democratic Party prospects in 2020. Nichols notes in his article that Trump won in 2016 largely because he sneaked out extremely narrow victories in three traditionally Democratic states—Wisconsin, Michigan, and Pennsylvania. His victories were narrow—0.7 points in Wisconsin and Pennsylvania and just 0.2 points in Michigan.
Now fast forward to 2018. There were six major races in the three key 2016 states Trump in 2018. Democrats won ALL of these races.
“Three Democratic senators—Wisconsin’s Tammy Baldwin, Michigan’s Debbie Stabenow, and Pennsylvania’s Robert Casey—all won with ease. Three Democratic gubernatorial candidates—Tony Evers in Wisconsin, Gretchen Whitmer in Michigan, and Tom Wolf in Pennsylvania—were also winners.”
Additionally, progressive Democrats won the races for Attorney General in both Michigan and Wisconsin.
If Democrats have similar success in these three states in 2020, Trump is going to find it very hard to win a second term.
