You can't look at California, New York, New Jersey, Maryland, Illinois, Oregon, Washington, Massachusetts--states who have these very long-term Democrat majorities, and tell me we have a representative anything! Those places will likely never turn back to any kind of balanced representative rule. They pass whatever the hell they want and the only pushback is through our Federal courts who often take years to produce meager relief.
It's not "getting bad" it "is bad."
