Maybe they will start to realize the persistent election cycle is not a good thing. I would love to see a ban on all election campaigning until 90 days before said election but that wouldn’t get past a 1st amendment challenge.
Just do publicly funded elections, including things like publicly funded frequent small debates where the candidates had to appear as reasonably competent adults who could defend their ideas, and resurrect some of the regulations like the fairness doctrine and caps on media consolidation
The dogshit quality of the current election coverage is mostly a problem because it is the only type of coverage that is available. I think if there was a widely available and well funded type of election coverage that wasn’t this cash grab horse race ad supported bullshit, the bullshit would have to compete against it and would lose and improve as a result.
If it's robust enough that it actually limits campaign spending without loopholes, then that alone might do it. Campaigns would have to use their funds more strategically, and the best time to spend is in the weeks before an election, not a year out.
