That's why the campaign is now handing out wrist bands as makeshift cheat sheets. The bands read, "Murkowski, fill it in, write it in."
While Murkowski worries about voters spelling her name, her rival, Miller, is putting his best hope in Alaska's most famous political voice, Sarah Palin. She's headlining a Miller event tonight.
"Of course, she's more important than other supporters. She carries a great deal of weight even in this state," he said.
Palin is pushing hard for a Tea Party victory in her own backyard. She addressed her own ambitions in an "Entertainment Tonight" interview airing later today.
"I have not decided what I'm going to do in 2012. I don't think any of the potential candidates have. If there's nobody else to do it, of course, I would believe that we should do this," Palin told "Entertainment Tonight."
As Election Day nears, it's possible that votes for Miller and Murkowski could cancel each other out and hand the race to a little-known Democrat, Scott McAdams.
Polls suggest it's a tight race, with analysts saying that any of the three candidates have a good shot at winning. There's also uncertainty surrounding the write-in process.
If Murkowski wins, she'll be the first write-in candidate elected to the Senate since 1954.
