JUNEAU -- After keeping a relatively low profile lately in Alaska's hot U.S. Senate election, Sarah Palin emerged Monday to take aim at write-in candidate Lisa Murkowski.

In a Palin Facebook post, the former Alaska governor attacked Murkowski, the incumbent senator with whom she's tangled politically in the past, talked up Republican nominee Joe Miller and made a fundraising appeal for Miller. The post was entitled "Lisa's Gall vs. Joe's Honor."

"I have never seen a candidate stoop as low as was seen last night in Alaska's senatorial debate," she said, adding later: "I find it astonishing that a sitting U.S. Senator from Alaska would challenge the honor of a decorated combat veteran."

That alludes to Murkowski asking Miller during a candidate forum Sunday night whether he believed his instructors and classmates at West Point would believe he had lived up to his code of honor in light of what she called his lies about her record during the primary and his acknowledgment he'd been disciplined at the borough.

Palin's political action committee has given Miller $10,000 this cycle, and she was a key endorsement for Miller before the August Republican primary, in which he narrowly defeated Murkowski.

Besides Palin's endorsement of Miller, the conflict between her and Murkowski includes Murkowski's criticism of Palin's mid-term resignation as governor in July 2009.
