The Sarah Palin buzz may be in danger of fizzling out, after the Alaskan State Senate approved the hiring of an independent investigator over the firing of the state Public Safety Commissioner.

The controversy is over whether Palin, or someone close to her, pressured Monegan to fire a state trooper who got a divorce from Palin’s sister.

Team Palin, of course, denied the accusation.

The end of the article does make the point that the investigation could be the death blow to any Palin-for-VP move, even if the story doesn’t hold water:

One reason it might is that with the investigation just beginning, there isn’t enough time to clear Palin’s name before McCain has to make a decision. Going into the fall with a running mate under investigation isn’t the best move.
