It’s because we can vote by mail now. Biden was the only one on the ballot in my city, no down ballot positions at all. I voted since I just had to drop it in the mail, but I wouldn’t make a trip out in February to vote for someone running pretty much unopposed.
The prefixes “cis” and “trans” are from Latin: “this side of” and “the other side of”, they are opposites and have been used in chemistry for decades.
