Mitch McConnell really deserves one.
Reid-McConnell Parallel Lives.
The more I think about this idea the more I like it. These are guys who were each other's chief antagonists in the Senate for ten years--2007 to 2017, Frist's retirement to Reid's own--longer than any other pair of Senate party leaders (Rayburn and Martin have them beat in the House). Hypercompetent partisan hacks preceded and (in McConnell's case probably) succeeded by people seen as at least a little bit more congenial and policy-oriented but not as good at the technics of the job, roughly the same age, families struggled financially in their childhoods (McConnell because he had polio, Reid for more "baked-in" class reasons). I'm sure there are other similarities as well.
