Does Sarah Palin's political future lie in Arizona?

(azcentral.com) - All of a sudden, there’s a lot of speculation that Sarah Palin’s political future runs through Arizona, the home state of her 2008 presidential running mate John McCain and where her daughter Bristol Palin recently bought a house.

On Tuesday, state Rep. Steve Farley, D-Tucson, forwarded a rumor that Palin was contemplating coming to Arizona to run for retiring Republican U.S. Sen. Jon Kyl’s open seat in 2012.
