Former Alaska governor Sarah Palin's One Nation bus tour is on the road again, and it's headed for Iowa — just in time for one of the most-watched pre-2012 weekends.

The Ames Straw Poll, a prominent all-Iowa Republican straw poll, is set for this Saturday at Iowa State University. Rep. Michele Bachmann (R-MN) and former Minnesota governor Tim Pawlenty will be in town for the poll, as will Rep. Ron Paul (R-TX). Former Massachusetts governor and GOP 2012 frontrunner Mitt Romney will deliver a speech to open the Iowa State Fair. Those candidates, as well as four others, will participate in a debate Thursday night.

Keeping with the spirit of the first leg of the bus tour, Palin has not released a schedule, and is not officially slated to speak anywhere. She released a video Wednesday evening prominently featuring her tour bus and images of small-town America. (Embedded below.)

"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," a statement on read.

Palin's name is not on the ballot for Saturday's poll, nor is she participating in Thursday's debate.

In addition to the conservative festivities in Iowa, Texas Gov. Rick Perry will be in South Carolina Saturday to announce his intention to run for president, and President Barack Obama kicks off a heartland bus tour next week.

It is rumored that Palin will visit the Iowa State Fair Friday. Palin has not announced whether she intends to run for the presidency, nor has she announced whether she will partake in the fair's signature delicacy, deep-fried butter on a stick.
