Kentucky Republican Sen. Rand Paul, in another sign he will run for president, called front-running, potential Democratic candidate Hillary Clinton a “war hawk” likely to scare 2016 voters who are tired of U.S. military intervention in the Middle East.

Paul, a leading anti-interventionist, predicted in an interview aired Sunday on NBC’s “Meet the Press” that the 2016 White House race will be a “transformational election” if Democrats nominate “a war hawk like Hillary Clinton,” a former Obama administration secretary of State.

The Libertarian-mind Paul, a first-term senator, last year opposed President Obama’s call for military action in Syria.
