Michele Bachmann's presidential campaign is all in in Iowa. A sure sign: Senior adviser Andy Parrish's Facebook page now lists his address as "West Des Moines, Iowa." Two sources close to the situation confirm that Parrish is not only moving to Iowa, but is bringing along his pregnant wife and child. Parrish has served as Bachmann's congressional chief of staff and thus qualifies as one of the big guns of her campaign. Parrish will be Bachmann's principal caucus organizer, starting with the critical Ames Straw Poll in August, one of the big milestones in the GOP presidential nominating contest .
