The election will be November 3, 2020. Not too far away.
A big turnout?
Hard to say with the pandemic. I vote by mail, so it won't be a problem for me. But, if I had to stand in a socially distanced line all day long, I might not be so patriotic.
Also, keep in mind that the popular vote doesn't mean anything in the US. Hillary Clinton won the popular vote by 3 million, yet due to the Electoral College BS she lost to Trump by small margins in only 3 key critical States.
I'd be delighted and surprised if Joe Biden wins due to the conditions aforementioned. However, I'm getting ready for another 4 years of Donald Trump. It will be hard psychologically to have Trump rule for another 4 years.
