Senate Seniority by State Delegation

AN INTERESTING chart crafted by the University of Minnesota’s Humphrey School of Public Affairs ranks Senate state delegations by seniority.  “Interesting” because the order is susceptible to great flux.  Consider Massachusetts, which soon will plunge from 14th to 50th once Senator Kerry takes up the reins of the State Department.  Or Hawaii, which “in a matter of a few weeks…dropped from the longest-serving in the nation with over 72 years of experience between Inouye and Daniel Akaka all the way down to #50 – with just 18 days of collective Senate service as of Monday between newly-elected Mazie Hirono and the appointed Brian Schatz.”
