What is wrong with you, man?
Stennis was a powerful advocate for Mississippi, our military and the space program. Like many Southern Democrats, he was opposed to the major civil rights legislation of the 1950s and 1960s, but he rehabbed himself later in his career. He voted to support the extension of the VRA in 1982, was important in sinking the nomination of Robert Bork, and even campaigned for Mike Espy during his 1986 Congressional campaign (Espy would become the first Black congressman from MS since Reconstruction).
And despite all the segregationism, that's good enough for you to see him not just as a good senator, but as the best senator of all time.
Not the best, my favorite. See OP. 
Well, I think it would be weird for the two to be different.
There is a reason "favorite" and "best" mean different things.
"The segregationist isn't the best he's just my favorite" isn't the defense you or Del Tachi thinks it is
