In WA and OR we vote by mail. It is secure, and there has never been anything like the kinds of problems Trump claims. Quite simply, he is just lying... as usual.
When is this nightmare going to end?
The "Spanish Flu" pandemic lasted three years (1918-1920). Hopefully we know more now.
I expect it to fade a bit at the end of summer, come back in the Fall/Winter and assuming everyone finally gets on board with prevention, it could end by the end of Summer 2021. I think there are just too many stupid people for it to end sooner than that.
