At some point folks gonna have to accept that a large part of the electorate is just regressive and no amount of good policy or messaging it going to change that.
Regarding the economy:
Dems hold advantages in healthcare and looking out for the middle class.
But voters are stupid. They believe Republicans will create more jobs despite Biden creating more job than any other modern president.
Couple the idea that Republicans will bring down inflation with the fact that inflation is a direct result of Republican policies of the people they voted out and you see voters Just like change for the sake of change.
