Perry is not, in my opinion, a potential president for all Americans.

Perry has expressed his views on non-Christian religions. Perry attended a service at the Cornerstone church in San Antonio, conducted by Rev. John Hagee. During that service Rev. Hagee stated, “If you live your life and don’t confess your sins to God Almighty through the authority of Christ and His blood, I’m going to say this very plainly, you’re going straight to hell with a nonstop ticket.” Perry was asked if he agreed with the comments, and Perry responded:

“It is my faith, and I’m a believer of that”.

Perry rubbed salt in the wound by explaining that there was nothing in the sermon with which he took exception. Perry explained that he believes in the inerrancy of the Bible and those who reject Jesus Christ as their savior will go to hell.
