To date, most of the news coverage around Trump has been his defense team's fumbling failures to make a compelling case.
Lemmyites are happy with this prevailing view for the time being. But if the increasingly right-wing dominated press decide to change their tune, we could easily see a "Trump is being persecuted unfairly" narrative gain ground in 2024, the same way that "Hillary Emails make her unfit for office" gained ground in the run up to 2016. Just depends on which way Jeff Bezos's WaPo, Elon Musk's Twitter, and Bill Gates's NBC decide to swing as we head into the general election season.
You're absolutely right about voters not being legal experts. And that's going to leave them increasingly vulnerable to whatever prevailing media narrative swamps them in November.
