You obviously don't know Alaska politics, so I will explain. Almost 60% of Alaska's voters are not aligned with either major party which means that THEY are the majority here, which is why I keep saying that Alaska is a purple state.
Joe Miller is extremely right-wing, obviously, and only won the Republican primary because of a ballot-bait measure regarding parental notification for teenage abortions which was on the primary ballot and brought out the fundies in droves. Lisa has always positioned herself as a moderate (although you wouldn't know it by her votes over the past two years, especially), and so she has been very, very actively courting the moderate independents and Democrats who are afraid of Joe Miller, votes that would have undoubtedly gone to Scott McAdams if she hadn't re-entered the race.
Miller's base is solid and isn't going anywhere. Lisa knows that in order to beat him, she has to woo away as many Democrats and independents as she can, and she's pulling out every trick in the book, including this attempt to virtually campaign within the polling booth, which is strictly prohibited by our election laws. There has NEVER been a list of write-ins posted inside the polling stations.
For some of her dirty tricks, just check out this story from a couple of days ago.
http://www.themudflats.net/2010/10/22/lisa-liar-pants-on-fire-murkowski-makes-false-claims-about-endorsements/ She was forced to apologize for lying that these prominent Democrats had said they were going to vote for her, and she lied saying that she had Patty Murray's support. She didn't clear the ad with any of the people who she quoted. She is desperate.
As Shannyn Moore and others said after Lisa announced her write-in campaign, Lisa is attempting to split the sanity vote, so in reality her write-in campaign hurts Scott McAdams more than it hurts Joe Miller.
She's a weasel of the highest order, and I would do anything to see her gone.
