Just something for the statheads (recognizing the politics of BBWAA voters):
When Seaver was elected to the Hall of Fame in 1992, he was on 98.8 percent of the ballots, which was a record that stood since 1936. Cobb got 98.2 that year. Ruth and Wagner (both 95.1) were also elected that year. Ryan tied Seaver at 98.8 in 1999.
That record remained until 2016 when Griffey garnered 99.2. Rivera got 100 percent in 2019 and Jeter 99.7 in 2020. Of the players mentioned above, excluding Cobb and Wagner, all of the highest vote-getters had New York connections. I don't think it's a coincidence. I also don't think it matters one bit. All earned everything they got.
Some other numbers: Johnson got 97.3 percent in 2015, Aaron 97.8 in 1982 and Mays 94.7 in 1979.
