“They are looking at how that would work if there are different iterations of her name, whether it’s Senator Murkowski or Lisa or Lisa M.,” said Steve Wackowski, a spokesman for her campaign, listing a few possibilities.

“If I can determine voter intent, then the ballot would be counted accordingly,” Ms. Fenumiai wrote in an e-mail. She declined to say specifically what versions of the senator’s name would be accepted.
