Since the indictment, Alaskans aren't feeling as warm towards Stevens -- that's no surprise. The percentage of voters with a positive impression of the incumbent fell from 55% to 44% in Moore's second poll. His negatives also rose accordingly -- from 38% to 48% two weeks later.
Despite his favorables taking a hit, Stevens still has a commanding lead in the GOP primary:
"Other" presumably includes self-funding beardo Vic Vickers, whose frequent swipes against "Big Oil" aren't likely to get him very far in a resource-dependent state.
Things are certainly looking good right now for Mark Begich.
Bonus finding: In the 7/18-22 poll, McCain leads Obama by a mere three points in the state -- 47% to 44%.
