Sarah Palin says she’s serious about her campaign for the U.S. House, telling The Associated Press that her unique place in American politics would put her in a stronger position representing Alaska in Washington.

The husband of former Alaska governor and one-time vice presidential candidate Sarah Palin has apparently filed for divorce, according to a report. Todd Palin, 55, cited an "incompatibility of temperament between the parties such that they find it impossible to live together as husband and wife," in a document filed Friday in Anchorage, according to the Anchorage Daily News. The filing uses initials, but the couple's wedding date and the birth date of son, Trig Palin, match, the paper reported. Sarah Palin, also 55, was elected governor in 2006.
