MOBILE, Ala. (AP) — Former presidential candidate Rick Santorum of Pennsylvania has endorsed conservative writer and former Congressional aide Quin Hillyer of Mobile for a soon-to-be vacant south Alabama Congressional seat. Santorum said Tuesday that he supports Hillyer's position on strengthening America's economy and for his standing up for American values. Santorum says he plans to join Hillyer on the campaign trail and tell Alabama voters why Hillyer would be "the right conservative" to serve in the First Congressional District seat. The Congressional seat is being vacated by Jo Bonner, who is resigning in August to take an administrative position with the University of Alabama.
