Sarah Palin's husband is pulling the plug on their marriage -- he has filed for divorce after more than 30 years together.
Todd Palin filed the docs last Friday in Alaska's Anchorage Superior Court, where he asked a judge to dissolve his marriage due to "incompatibility of temperament between the parties such that they find it impossible to live together as husband and wife."
That's a mouthful to essentially say, "irreconcilable differences." Todd's filing asked for joint legal custody of their only remaining minor child, their son Trig, who is 11. The couple has 4 other children together.
