It doesn't change the fact that Trump is far more responsible and completely abdicated his leadership responsibilities, but I can think of about a dozen things Dems did wrong. They were overly obsessed with business shutdowns, eager to capitalize on it for political purposes, willing to distort the truth to try to influence behavior, and unwilling to look at ways to encourage safer activities.

For an example, instead of shutting down churches and triggering a showdown, blue states should have worked with them to facilitate outdoor services. I don't have any illusions that such a tactic would have worked if any Republicans had to be involved, because they won't work with Democrats on anything, but a lot of states are unilaterally blue and didn't even try. Instead, they focused all their time and energy deciding exactly how much business shutdown was needed, as if that were the only club in the bag.

Even without Trump's naked self-interest looming over everything, the choice basically became between murdering mom-and-pop businesses or murdering Mom and Pop themselves. It didn't have to be that way.
