Florida Senator Marco Rubio launched his presidential bid Monday evening, and he made his pitch very clear: He represents the future. “Now, just yesterday,” he said, “a leader from yesterday began a campaign for president by promising to take us back to yesterday. Yesterday is over, and we are never going back. We Americans are proud of our history, but our country has always been about the future.” Clearly, this was a shot at Hillary Clinton’s campaign. Nothing says “yesterday” like a Clinton running for the White House for a fourth time. Political analyst Charles Krauthammer likewise observed, “This was clearly a speech about old and new. This goes back not just to Clinton in ‘92 or Obama in '08; this is to Kennedy in 1960. Remember, in his inaugural address he said the torch has been passed to a new generation. … Basically he’s saying, 'Do you want old or do you want new?’”
