Michael, what you say here may be true (not very nuanced, but true), but I would be cautious about the meaning of this for 2020. At the moment, many election models predict a Trump victory over any currently known candidate for the next presidential election. The idea that the electorate can or will coalesce around someone who can beat Trump was tested in 2015-16, and failed repeatedly. The will of the majority right now seems to be swayed by pop culture, not by Catholic social teaching and values.
If the course of history is going to change, we need to do more than point out the failures of our elected officials. We need to identify and support candidates who can win. At the moment, I don't see anyone on the horizon, and the models are reflecting that. (Remember that models are not polls.) A lot can happen between now and then, but the idea that a decent, intelligent, experienced politician will emerge and win the day -- may be more a dream than an aspiration.
