During a 2012 joint appearance in Mexico City with then president Enrique Pena Nieto, I saw that the Mexican media was attacking him savagely. His critics argued that he was inexperienced and untested, a pretty boy with a TV-star wife. They were skeptical that his party, the ancient PRI, would reform the country and take on the drug cartels.Yet it was obvious to me that he had boatloads of charisma, a quick grasp of the issues and a self-deprecating humorous side. He combines Reagan's charisma with Obama's intellect and Clinton's political skills. This is a leader to watch.
