Ex-mayor Dan Sullivan supports incumbent Dan Sullivan’s Senate bid against third Dan Sullivan

Endorsement of Republican incumbent over challenger with same name adds twist to unusual campaign in Alaska

• Republican senator Dan Sullivan and Democrat Mary Peltola advance in Alaska Senate primary

Dan Sullivan supports Dan Sullivan against Dan Sullivan in Alaska's US Senate election, says a former Alaskan mayor who recently backed the race's Republican incumbent over a challenger sharing their name.

That development provided another of multiple absurd elements to Dan S Sullivan's campaign for a third term in the US Senate, which - beside Mary Peltola, a former Alaska Democratic congresswoman - has drawn opposition from Dan J Sullivan.
