Ahead of the 2016 presidential election, Democrats weren’t just optimistic because of the polls. They also spent quite a bit of time fiddling with sites like 270 to Win, exploring different scenarios with the electoral college, and concluding that Donald Trump’s path to the White House simply didn’t exist.
After all, the Clinton/Kaine ticket could lose several of the battleground states Barack Obama had won at least once — Florida, Ohio, Iowa, and North Carolina — and still win the election thanks to the “blue wall” in the Rust Belt.
Before 2016, in six of the previous six presidential elections, Michigan and Pennsylvania had voted Democratic. In Wisconsin, it was seven of the previous seven. So long as these three states remained in the “blue” column, Hillary Clinton would be the next president.
We now know, of course, that this didn’t happen. Michigan, Pennsylvania, and Wisconsin each went “red.”
Two years later, these same three states appeared to swing back in the other direction.
