(Olympia, WA)  --  Another Democratic elector in Washington state is joining a small group of electors nationwide who are seeking to prevent Donald Trump from becoming president.  Nineteen-year-old Levi Guerra, a Democratic elector from the town of Warden, Washington, says she and two other Democratic electors in the state will try to convince Republican electors in Washington to not vote for Trump but to cast ballots instead for a moderate Republican.  Electors in each state will cast their ballots on December 19th, in the final official phase of the 2016 presidential election.
