I think that Democrats skewing towards mail-in at the time gives this credibility, but I think there were too many anomalies to dismiss the entire thing. It doesn't look right to me.

It goes both ways though. In 2016, it was the other side calling fraud. 

I say this as an outsider who isn't a fan of Trump outside of entertainment value. 

One thing I will never understand is the persistence against voter ID, which would theoretically protect everyone involved.
