The issue is that even if you voted for the democrat every time, due to them not improving the living situation considerably you’ll always end up having the worse guy win at some point.
The only thing that would really help would be to finally start improving the living reality of the people.

True, but do democrats improve more than the previous republican made it worse? It doesn’t feel like it.
Also I wouldn’t use Healthcare as an example of something that works in the US
