(Special mention for Lindsey Graham, because he has been veering more towards the center in recent years than the way he started out. During the eight years he was in the House, and for the first 10 years he was in the Senate, he had an average ACU score of 89.6%. But for the years 2013 to 2019, inclusive, his scores have dropped way down, to an average of only 65.3%. This has brought his overall average for his entire career down to 82.8%. If he continues on the trajectory that he is currently on, his average may dip below 76% by the time he leaves the Senate.)
I've never seen a post so thoroughly disprove its own metric like this. Congrats!
