Months after Sarah Palin rode her constitution-themed bus into New Hampshire just as Mitt Romney was kicking off his campaign, the former Alaska Governor and 2008 Republican vice presidential candidate appears to be at it again.

In an email sent to supporters, Palin said she would travel to Iowa this week to visit the Iowa State Fair.

"The heartland is perfect territory for more of the One Nation Tour as we put forth efforts to revitalize the fundamental restoration of America by highlighting our nation's heart, history, and founding principles," she wrote.
