62 years since tri-state senators switched at once, one was George Wilson '28

January 1943 was the last time new senators began representing all three states. The three Republicans were Harlan Bushfield, of South Dakota, Kenneth Wherry, of Nebraska and George Wilson, of Iowa.

It is notable that the trio had short careers in the Senate. Bushfield died in office in 1948, while Wilson lost his re-election bid in 1948 and Wherry died in 1951 during his second term.

The growing crop of 2014 senatorial candidates no doubt envision longer careers in D.C.
