This was the whole point of the "staged corona virus" scare.

There are quite a few unproven whoppers in this article, to say the least, but I doubt that President Trump will have any trouble carrying these states again in 2020.  I just don't see people as being that wishy-washy.  If they were for him in 2016, they're likely to still be in his corner because if they've had their eyes wide open, they can see that the whole corona crap thing was "staged" just for the benefit of NOT letting Trump onto his very successful campaign trail.  He packed in more people than most arenas could hold, and that's a fact.  It will be a fact again, too, once he gets back into the swing, just wait and see.

The democraps are hideous liars and I think most people can see that.  If not, they were leaning left anyway.
