The latest on Hillary Clinton's possible presidential run: She'll decide by early next year. Or so she said when asked about it today at a forum in Mexico City , MSNBC reports. "I am going to be making a decision … probably after the first of the year about whether I’m going to run again or not," she said. She added that "vision" will be an issue in her decision, CBS News reports: "I will have to be convinced that I have a very clear vision with an agenda of what I think needs to be done, and that I have the experience and know-how to lead." The Mexico City event was honoring thousands of students funded by Telmex Foundation, a charitable organization supported by Mexican billionaire Carlos Slim. (Clinton has called the presidency "the highest, hardest glass ceiling.")
