I'm from Washington and while I'm familiar with the name... Inslee is pretty much a blank slate in a state of really bizarre politicians. Washington state actually liked Bernie over Hillary in the last election. It is like California... the most populated cities which are heavily Democratic, dominate the politics of the entire state.
Sure about that? Bernie Sanders did win the state of Washington caucus, but fewer than 30,000 Democrats voted in that. Hillary Clinton won the state of Washington's primary in 2016 over Sanders, when over 700,000 Democrats participated.
