He’s got a shot, thanks to The Quitter’s purge of Murkowski.

A new snapshot of the Senate race in Alaska, taken in the hours after Sen. Lisa Murkowski conceded the GOP nomination, shows Joe Miller running six points ahead of his Democratic rival, Sitka Mayor Scott McAdams.

The Rasmussen survey of likely voters shows Miller, a lawyer who is backed by Sarah Palin, with 50% of the vote and McAdams with 44%. The poll has a margin of error of 4.5 percentage points.

And that’s Rasmussen, so it’s probably even closer.
