MIAMI — Senator Marco Rubio of Florida announced on Monday that he is running for president, declaring that he is the best person to lead the United States into “another American century.”
Mr. Rubio made his announcement Monday evening during a speech here in which he presented himself as the embodiment of generational change who can unite the Republican Party’s factions and offer economic solutions for the 21st century.
At 43, the youngest candidate in the rapidly growing 2016 presidential field, Mr. Rubio cast himself as a forward-looking, next-generation leader — and an implicit contrast to Jeb Bush, 62, whose family has dominated Republican politics for nearly three decades, and Hillary Rodham Clinton, 67, the wife of a former president and the most likely Democratic nominee.
“Too many of our leaders and our ideas are stuck in the 20th century,” Mr. Rubio said, pointing to education and spending programs put in place by Democrats in the 1990s.
In a direct attack on Mrs. Clinton’s candidacy, which she announced Sunday, Mr. Rubio said: “Just yesterday, a leader from yesterday began a campaign for president by promising to take us back to yesterday. Yesterday is over and we’re never going back.”
