It's not Sarah Palin, according to a new survey from Hays Research. Sen. Lisa Murkowski's favorability rating continues to climb as Alaskans have taken a more unfavorable view of their governor, the 2008 Republican nominee for vice president.

Favorability Rating
Palin 54/42 (compared with 60/35 in March)
Murkowski 76/18 (compared with 72/20 in March)

The survey found that 30.5% of respondents had a "very positive" view of Palin, down from 34.9% in March, while 24.8% now have a "very negative" view, up from 21.2% in March. A survey conducted in May of 2008 pegged Palin's favorability rating at 86% -- a 32-point drop in just one year. Then, only 3% had a "very negative" view of their governor.

The new survey of 400 voters was conducted May 4 and 5, and had a margin of error of +/- 4.9 %
