Both senate races had vulnerable Republican incumebents, Democrats think they've got a strong challenger. Polling pretty much always showed Feingold with a decent edge over Johnson, same way pretty much all polling shows Kelly beating McSally. In the end, Feingold not only lost, but he significantly underperformed Clinton. Are Democrats being too bullish about this AZ senate race in 2020, or is ther soemthing that makes this significantly different?
Arizona, on the other hand, is much younger, less white, politically moderate, and more educated.
The two states are about exactly the same in terms of educational attainment, with Wisconsin actually being marginally ahead (29% vs 28.4% college-educated or higher, which are both lower than the U.S. average of 30.9%).
Of course, let's not forget that the Democratic base is minority voters and not college-educated White people.
