Three well-known candidates lead by former Alaska governor and vice-presidential candidate Sarah Palin have advanced to the general election in Alaska’s special House race, NBC News projects. Republican Nick Begich, the grandson of former Rep. Nick Begich, D-Alaska, and nonpartisan Al Gross, a surgeon, have also advanced to the general election, according to NBC News’ projection. In August, Alaska voters will rank four candidates to determine who secures the House seat for the final few months of the late Rep. Don Young’s term. Young held the seat for decades and died in March.
