TUCSON, Ariz. (AP) - John McCain is reuniting with his former running mate Sarah Palin, but not all Palin fans are happy about it. A handful of Palin supporters have set up outside a rally in Tucson featuring McCain and Palin. Former congressman and conservative talk-radio host JD Hayworth has launched a primary challenge to McCain saying the four-term Arizona senator isn't conservative enough for Arizona voters. Jennifer Leslie of Oro Valley, Ariz., says she's an avid Palin fan but will be voting for Hayworth in the August primary.
