The electors referenced are indeed Democratic electors, and they are supposed to vote for Hilary given she carried WA state. Supposed to but not required. Interestingly, if there were enough electors from the states Trump won who refuse to vote for him, and cast their vote for another Republican, the Democratic electors could join in to add their votes for that person, and possibly create a surprise outcome. 

Note that Trump isn't elected until those forecasted electoral votes actually are cast for him on December 19. None of the electors has to vote for him. Being party faithful, they won't likely cross party boundaries, but they could, for instance, cast their votes for Pence and make him President instead. Or pick another person.

Per the Constitution, only the Electoral college can determine the President and Vice President.
