Maybe Trump didn't "take the virus seriously enough" to stop it, but if so, then no one did.
The real question: Did he, and all the Dems telling us to live our lives normally during the impeachment trial...did they act reasonably given the circumstances. Maybe they did, by not taking it more seriously. But, if they didn't, then it was an epidemic of unreasonable behavior in D.C., on both sides.
I don't get how people can blame Trump for that, when those same people were saying it was no big deal, and moving forward with impeachment.
If he moved more quickly, and started shutting things down during the impeachment and during the primaries, you would be screaming about an autocrat trying to set aside the Constitution. All this is pure politics.
