My Hoover colleagues David Brady and Mo Fiorina gave a recent talk updating some of their work on polling American political opinions. I found this one particularly interesting. Notice how after President Obama's first win in 2008, the fraction of Democrats reporting that the economy is getting better jumped from 10% to 50%. The Republican fraction declined, though not as much. When Trump was elected in 2016, the Republican opinion jumped from 15% to 80%, and Democrats fell from 60% to 25%.
