Murkowski went on to lose the primary to Tea Party-backed challenges Joe Miller. Now Murkowski, who has embarked on a write-in general election campaign, is putting the ad out - in the most delicate way possible.
The minute-long spot opens with Stevens' daughter explaining that "my father made a campaign commercial for Lisa that was scheduled to run just days after we lost him."
"Putting our family before her campaign, Lisa made certain the ad did not air out of respect to my dad and our family," she continues. "Now, my family and I want you to hear for yourself how strongly he felt about the need to reelect Lisa."
The ad then shows Stevens, who says, in part, "we need Lisa and the seniority she's earned now more than ever." It then cuts to Murkowski, who, standing next to Stevens' daughter, thanks the Stevens family.
While write-in candidacies are notoriously difficult (and difficult to poll), a survey of likely voters from Rasmussen out yesterday suggests Murkowski is right in the thick of the race: Miller takes 35 percent of the vote in the survey, while Murkowski takes 34 percent. (Democrat Scott McAdams comes in third with 27 percent.) Less than a month ago, Miller led Murkowski 42 percent to 27 percent.
Alaska election officials have said they will take into account voter intent in considering write-in ballots. That means that even if voters misspell Murkoski's name , almost all votes for her will presumably count. Still, it is not clear that the support pollsters find for a write-in candidate will necessarily translate to the ballot box in the same way support does for a candidate whose name is actually on the ballot.
