With 33 percent of precincts reporting, Joe Miller, the Sarah Palin-backed veteran and former judge, is leading incumbent Alaska senator Lisa Murkowski in the Republican Senate primary 51.2 percent to 48.8 percent–or 21,364 votes to 20,362 votes. As John Fund reported Tuesday, Miller was “closing the gap,” but still down by double digits against Murkowski in the most recent polling. This would be a very big upset if Miller wins.

Update: With 50 percent of precincts reporting, Miller is holding his narrow lead over Murkowski,  51.8 percent to 48.2 percent.
