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?
Wisconsin was demographically and socio-politically moving to the right, starting with the Tea Party races in 2010. It happens to be a very white, very upper-middle-aged, and less-educated state.
Arizona, on the other hand, is much younger, less white, politically moderate, and more educated.
