(Olympia, WA)  --  Washington's state legislature is among the nation's most polarized legislatures in the nation, according to a Georgetown University assistant professor.  Researcher Boris Shor, who studies state legislatures across the U.S., says Washington had the third-most partisan legislature in the nation from 1986 to 2015, trailing only California and Colorado.  Shor told KING-5 that the two major political parties are pulling further apart, both nationally and locally, and it's a trend he doesn't see ending anytime soon.
