From Sean Cockerham in Anchorage ---

Lots of speculation today that Lisa Murkowski is about to launch a write-in candidacy for the U.S. Senate, but her campaign says it’s not a done deal.

“It’s fair to say we’re in a moment of pause but no firm decision has been made yet,” said Steve Wackowski, Murkowski’s campaign spokesman.

Fox News today declared that Murkowski was “expected to mount an independent campaign for senator.”

But the Fox report was based on an unnamed “senior official in Murkowski’s camp” who also told Fox he did not actually know whether Murkowski would wage a write-in campaign or simply retire.

"She's keeping her own counsel on this one. As far as I know, she's told no one," the aide told Fox.

Fox said it also had “another source” who expected Murkowski to run, but did not say that person had any firsthand knowledge.

Other publications haven’t gone as far as Fox, saying only that Murkowski is strongly considering a write-in bid. Murkowski herself has acknowledged she is considering that, although she called it high risk. There's been a lot of talk among Murkowski supporters in Alaska today, many of whom expect her to run and are waiting to hear what she has to say.

A write-in campaign would be difficult, although voters wouldn't necessarily have to spell Murkowski's name correctly.

"If I am able to determine the voter’s intent, then the ballot would be counted accordingly," Alaska Division of Elections Director Gail Fenumiai said.

But Alaska law doesn't allow voters to use stickers with the candidate's name.
