We're facing very complex problems that don't have simple answers. However, the other side is providing simple to understand solutions. The problem is those simple solutions are horrendous, and aren't actually solutions. Example:
Americans are struggling with low wages. The other side says its because of foreigners and moves to arrest and deport them. Simple right? Except you and I both know the low wages has nothing to do with immigrants, and instead on corporate America and captured politicians keeping wages low while productivity continues to rise.
If the other side simply gives simple "common sense" solutions that a typical American understands (even if its wrong), then that will be appealing to them instead of a realistic complex solution which promises far fewer benefits. What are Democrats to do here that can counter the infinite depth of lies of the other side?
Where in your example is the Democratic solution to this same problem? It seems like you're just arguing that people are too dumb to understand that Democrats always do what's best for them while here (and in your follow up reply below) state that the problems we face are essentially too complicated to fix so we shouldn't hold it against Democrats for not having solutions.
