National: The fascinating recent history of political primary ‘meddling’ | The Washington Post
Sen. Mark Begich (D-Alaska) would presumably like to run against Joe Miller (R) in the November election. Miller, the GOP’s surprising 2010 nominee who eventually lost to Sen. Lisa Murkowski’s (R-Alaska) write-in bid, emerged from that campaign extremely unpopular and now fares worse than his primary opponents in general-election polling against Begich. At the very least, Begich’s supporters see former state attorney general Dan Sullivan as the biggest threat in Tuesday’s three-way Republican Senate primary in the state, judging by ads run by the group Put Alaska First are any indication. The pro-Begich PAC has been hammering Sullivan, in a move that some Republicans critique as undue “meddling” in their primary. A better descriptor than “meddling” might be: How politics works.
