20 Most-Cited Constitutional Law Scholars in the U.S. for the period 2013-2017 (CORRECTED AND UPDATED 8/21)

Based on the latest Sisk data, here are the twenty most-cited constitutional law professors in the U.S. for the period 2013-2017 (inclusive) (remember that the data was collected in late May of 2018, and that the pre-2018 database did expand a bit since then).  This time around I've defined the "constitutional law" category a bit more carefully and also checked more carefully the percentages of citations that appear to be in the field for some highly-cited scholars; I will also be expanding the other public law coverage to reflect contributions that belong more clearly to, e.g., administrative law, legislation etc. (I will also be adding a separate ranking for election law).  Numbers are rounded to the nearest five.    Faculty for whom 75% or more of their citations (based on a sample) are in this area are listed; others with less than 75% of their citations in this field (but still a plurality) are listed in the category of "other highly cited scholars who work partly in this area."
