The Democratic party is trying to rebrand itself, but it is still floundering around on how to message that they are the "real populists". I suggest they pose it two ways. Trump conned you; he is making it harder for the middle class to cope, not easier and the Democratic Party is fighting for making your life easier. It is both a negative and positive message and the dems have got to deliver a positive message better than what they are planning to do. They need to put their plan under a forceful banner...of making life easier than harder and tie each issue to that banner.

So many of those rules and regulations were crafted to protect consumers and the general population from exploitation by unethical and anti-consumer and health-harmful business practices. How many more Love Canals, unsafe at any speed vehicles, mortgage /foreclosure disasters, loss of job safety protections, and deceptive trade practices will we see in the future?
His following executive order to rollback of Dodd-Frank requirements of feduciary responsibility of those in the financial sector to put their clients' best interests ahead of their own financial gain. That means when advising clients where the invest their money, the financial professionals can sell customers products which give the advisors higher rewards, not the clients. This is an overt attack on consuer interests and populist concerns.
