Marco Rubio ended his campaign for president after election results showed him a distant second in his home state of Florida Tuesday, slipping the announcement into a concession speech that reflected on his White House bid, assessed the tone of American politics, and advocated a robust conservatism.

“America needs a vibrant conservative movement. But one that’s built on principles and ideas, not on fear, not on anger, not on preying on people’s frustrations,” Rubio said on the grounds of Florida International University in Miami.
