Washington (CNN) - Iowa GOP Chairman Matt Strawn said former Alaska Gov. Sarah Palin better get to work in Iowa if she wants to run for president.
"This isn't the type of process where you can give speeches to thousands, or you can be behind 30-second ads or even Facebook posts," Strawn said in an interview on CNN's "John King, USA" Thursday. "You need to be on the ground, letting Iowans look you in the eye and kick the tires."
The 2008 Republican vice presidential nominee hasn't announced a White House bid, but she made news Wednesday when confirming that her "One Nation" bus tour will roll into the Iowa State Fair this weekend.
The Hawkeye state hosts the first caucus in the 2012 primary and caucus calendar.
"She needs to do those things that have proven what you need to do to be successful in the Iowa caucuses, which is get here and actually let the voters ask tough questions," Strawn said.
Palin will be in Iowa during a crucial weekend for the 2012 presidential field. The second presidential debate takes place Thursday night in Ames, a city that's also home to the high-stakes straw poll on Saturday.
While she hasn't thrown her hat in the ring, Palin has remained at the forefront of recent political issues, weighing in on the debt deal and Standard and Poor's downgrade of the U.S. credit rating through media appearances and posts on her Facebook page.
