Sarah Palin-Endorsed Alaska Senate Candidate Trailing Lisa Murkowski By Wide Margin

Just how much is a Sarah Palin endorsement worth in Alaska?

At least as far as the state's U.S. Senate GOP primary is concerned, not very much it seems.

Incumbent Sen. Lisa Murkowki is leading challenger Joe Miller 62 percent to 30 percent, according to a Ivan Moore Research poll. (More than half of the Alaskans polled said that they had no impression of Miller.)

Miller not only has Palin's backing but also the support of the Tea Party Express heading into the Aug. 28 primary.

The National Journal reports that "Palin initially said she would back Murkowski and cut the senator's campaign a check. But this spring, Palin decided to back Miller after her husband, Todd Palin, hosted a Miller fundraiser in Wasilla."

Another recent survey points out Palin's dwindling popularity in her home state.

Palin, who was once extremely popular as governor, is now viewed unfavorable by 47 percent of Alaskans compared to 41 percent who view her favorably.

The Ivan Moore Research survey was conducted July 7-11 and polled 647 registered voters, including 303 Republican voters in Alaska.
