I think Washington and Iowa had voted the same since 1948 or something, this finally breaking it...But you have Oregon instead???

I guess I could be wrong.

Washington voted for Humphrey in 1968, while Iowa and Oregon voted for Nixon.  The previous version had Washington joining the pair of Iowa and Oregon in 1972.  This version now shows Washington joining Oregon alone.
