A Washington state Democratic superdelegate is supporting Sen. Hillary Clinton for the party’s presidential nomination.

State party Vice Chairwoman Eileen Macoll of Pullman says Clinton has the best chance of successfully ending the Iraq war.

Macoll’s announcement Thursday bucks a recent trend of Washington superdelegate endorsements for Sen. Barack Obama.

Macoll is the sixth Washington superdelegate to endorse Clinton. Seven of the state’s 17 superdelegates have endorsed Obama, while the other four are officially uncommitted.

Superdelegates make their own choice about their vote for the nomination - other delegates to the Democratic national convention are pledged based the state’s caucuses, which Obama won.
