These tables accompany Washington’s 1970 Abortion Rights Victory: The Referendum 20 Campaign. Compiled from the Senate Journal and House Journal they show how each member of the legislature voted on SB 68, the measure that sent Referendum 20 to the voters in 1970. The color coding makes interpretation easy. Green and bright red are reserved for King County legislators, green signifying yes, red no. Purple and blue are for yes votes from other counties, purple for Republicans voting yes, blue for Democrats. Black signifies a no vote from a member of either party outside of King County.
It is quickly apparent that this was a bi-partisan measure. Throughout the state Republicans and Democrats split both the yes and no votes. In King County, which fielded more legislators by far than any other county, Republicans were more likely than Democrats to support the abortion reform measure.
