The gerrymandering issues are part of a larger play. Billionaires have corrupted and corroded every avenue for positive change over the last 60+ years. They have created so much paranoia and distrust in the government that even when something positive happens, it’s twisted to the negative. Biden did make some positive plays and no one cared because the entire apparatus of social discourse is diluted by misinformation and disinformation. America is an oligarchy now.

Until billionaires are put in their place by an ideological unionization across society, nothing will change. Trump is just their brazen puppet and is totally replaceable. The oligarchy needs to be brought down and people need to learn to see through their manipulations before real change is possible. They have been working for this moment under a collective ideology for a century: https://en.wikipedia.org/wiki/Dark_Money_(book)
