The Sarah Palin bump is over in the polls for GOP running mate John McCain. Now husband Todd Palin has decided he's above the law. This is not good news for Republicans fighting to attract independent votes in November's presidential race.

Todd Palin says he will refuse to obey a subpoena from an independent investigator for the state legislature in Alaska. The reason: Palin claims he's too busy out on the campaign trail. What a limp excuse.

The investigation centers on whether Sarah Palin or her staff abused their powers when Palin, as governor, fired her public safety commissioner.

Critics say it was because he failed to get rid of a state trooper who was involved in a nasty divorce from Palin's sister.

Investigators want to know how much involvement Todd Palin had in pressuring for the firing of either the commissioner or, before that, the trooper.

If Todd Palin continues to thumb his nose at the law, he can be found in contempt of the proceeedings.

But he may win the battle obviously being waged now by the Palins and McCain's handlers. They hope to keep the independent investigation from reaching a conclusion before Nov. 4.

Problem is, the longer this matter stays in the public view -- and the Palins not cooperating with it -- the worse it looks for McCain's image as a law-abiding do-gooder.
