While reading Daniel, I see in ch 6:2 that the new king, Darius, appointed Daniel as the first among three presidents in his kingdom. Also mentioned were princes, governors, counsellors, and captains, verse 7. So Daniel is a president, and knows the meaning and the difference between a president and a prince. So if he later wrote what the Lord told him, that a prince would come, who we assume to be the AC, then we should believe him and not guess that the AC is a president, because Daniel knew the difference! I think then that we should take the Bible literally and believe that the man to come will be a prince, literally. So that rules out  Bush and Clinton, but leaves the door wide open for  Prince Charles or his son William, or Prince El-Hassan bin Talal of Jordan. Or the Prince of Syria.
