An addendum to earlier posts, here and here, adding the most recent poll results from the 5 May survey.
The telephone survey polled 400 Alaskans over 18 years old, selected randomly. If no one was home, up to four consecutive attempts were made to reduce non-response bias. The margin of error is 4.9% and the confidence level is 95%.

The downward slide continues. She has suffered a 45% loss of people who rate her “very positive”, and the number of people who view her “very negatively” continues to grow.
Her overall “positive” rating (“very positive” + “somewhat positive”) was around 80% throughout much of 2007 and 2008. Once she started campaigning for vice-president those numbers started to nosedive.
Conversely, her negative numbers are rising, especially the “strongly negative” replies.
