Sarah Palin, Mike Huckabee, Haley Barbour and, now, Mitt Romney.

Romney, 2008 GOP presidential candidate, is the latest in a parade of possible 2012 Republican candidates to plan a stop in the Gopher state.

The former Mass. governor will stop in Gov. Tim Pawlenty's home turf on April 9 as part of his book tour for "No Apology: The Case for American Greatness." He'll come for a private roundtable with the Freedom Foundation, where tickets will go for as much as $5,000, and also make a public speech, according to his Web page.
