Reminds of when I worked for the DSCC when Howell Heflin was retiring & Sessions was running for his seat: his staff told me Sen. Heflin was proud to keep Sessions off the federal bench because "At the risk of offending every rock in the world, that boy's dumber than one." After Sessions' eleciton, I heard Heflin say something along the lines he wasn't too upset Jeff Sessions replaced him, for after all, being a judge was one thing but intelligence was not something the Senate had in any abundance.
That is some high quality snark.
Now go read the Chait article.
