(AP) Former state Attorney General Dan Sullivan became the latest mainstream Republican to turn back a tea party challenger, winning the Alaska GOP primary to become his party's candidate to take on U.S. Sen. Mark Begich in the fall.
Republicans see the Alaska race as a key contest in their attempt to capture the Senate majority from Democrats.
Sullivan entered the primary the presumed front-runner, with the backing of national GOP powerbrokers and a huge cash advantage over his rivals.
