Despite extreme censorship, data and information are more available than ever (whether or not people are smart enough to understand is one thing, but let's assume ~60% of adults are).
The democratic policies are so bad for Americans, their party cannot survive in 2020+ unless one of two things happen: 1) Voter manipulation by some means. Or 2) They can successfully steer people from becoming aware of their utterly terrible policies by using fear and guilt to focus the population on racism, COVID, or weather.
Right now they are winning on #2, but when you look at every meaningful metric, they're failing America left and right.
And the Republicans have the winning strategies, but they're so bad at using this data collectively to convince the masses that there are tangible things at stake other than racism, COVID, and Climate. The Reps have a lay up given how bad democrats policies are, but they're shooting half courters.
