(CNN) - The witching hour has come early in Alaska, in the form of a Halloween web video by Republican Senate nominee Joe Miller.
Miller won the GOP primary earlier this year against incumbent Sen. Lisa Murkowski who is now running as an independent write-in candidate.
"My opponent is not a witch, but she sure has conjured up some pretty crazy votes in D.C.," Miller says at the beginning of the ad, a reference to Delaware Senate candidate Christine O'Donnell saying over a decade ago that she "dabbled in witchcraft."
Halloween-themed music then plays while Murkowski's Senate votes are explained in an eerie voice before a boiling cauldron and flying bats.
"Washington is boiling over with special interests and nightmarish deficits for as far as the eye can see," the narrator says.
Miller also describes Murkowski as "she who must not be named."
Murkowski's Communications Director Steve Wackowski responded to the video.
"Why is Joe taking his lead from Christine O'Donnell?" Wackowski said in an email to CNN, going on to tout Murkowski's write-in campaign. "He must realize that Alaskan voters do know what her name is and that they will be coming out in force on November 2nd to fill the oval and write it in."
Miller and Murkowski will face Democrat Scott McAdams in the November election.
Recent polls show the race between Murkowski and Miller is neck-and-neck.
