The Democrats are stuck in a hard spot.
It was not messaging that was the problem.
If something looks like s and smells like s all the messaging in the world is not going to convince me that is would be delicious and I will be happy eating it
If they want to be successful long term the may want to ditch billionaires and be straight with Americans and deliver this message.
You want to get rid of corruption, we know where to start, campaign financing and legislative ethics

Eliminate PAC's
Eliminate any global corporation financing
Mandate all electronic and print advertising only contain candidates positions and expected results from those positions
Only candidates can run electronic adds
Candidate can not run attack adds
Social media platforms can not amplify political posts directly or indirectly

Ban lobbyist
Ban ownership of stocks
Restrict ability to work in private sector after leaving office

When a citizen invest their vote in a representative they expect to be represented
Much like buying a robotic vacuum, you expect the vacuum to clean your house and would be very upset if it only cleaned the richest house in the neighborhood and not your.
Especially when it comes and tells you what a great job it is doing and how that is soooooo gooood for you......

Cut ties with the global corporations and the Robber Barons and start representing your constituents
I oppose the political elites, global corporations, and Robber Barons
I stand with all Americans Red,Blue,& White
Take back America
