Including people who are so old that they can't even think straight anymore? Elders doesn't necessarily mean those who have been there ~30 years and/or are literally dying in office. There is a difference.
Lol I was actually going to add "but perhaps 80 IS too old?"
But it's hard to say. After all, the word literally means being old. In fact, it means the OLDEST members of society. So literally having 80 year olds IS how the Senate is supposed to be.
What do you think of simply repealing the 17th amendment and going back to having state legislators select Senators? Too partisan to do today?
