I don't get it. No chance for them in the state and the House races aren't tight, and he doesn't need to poke Harkin with a stick. From what I understand, Palin's appeal to the radical base is limited in Iowa. Refueling maybe?, or just a chance to get foreign experience? Move on, nothing to drill here.
Does he want another fight with Sen. Grassely?
John McCain, Charles Grassley Physical Altercation Confirmed By Washington Post
It was early 1992, and the occasion was an informal gathering of a select committee investigating lingering issues about Vietnam War prisoners and those missing in action, most notably whether any American servicemen were still being held by the Vietnamese. It is unclear precisely what issue set off McCain that day. But at some point, he mocked Grassley to his face and used a profanity to describe him. Grassley stood and, according to two participants at the meeting, told McCain, "I don't have to take this. I think you should apologize."
McCain refused and stood to face Grassley. "There was some shouting and shoving between them, but no punches," recalls a spectator, who said that Nebraska Democrat Bob Kerrey helped break up the altercation.
