WASHINGTON, May 10 (UPI) -- Presidential candidate and current senator Bernie Sanders has pledged not to accept support from super PACs.

Sanders did not criticize Hillary Clinton for her ties to super PACs. "I don't think we're going to outspend Hillary Clinton or Jeb Bush or anybody else, but I think we are going to raise the kinds of money that we need to run a strong and winning campaign," he said on Sunday on CBS's "Face the Nation."

If he became president, Sanders said he would base his Supreme Court nominations on individual positions about money influencing politics. "I do not believe that billionaires should be able to buy politicians," he said.

Sanders explained what he means when he calls himself a "democratic socialist," saying that he simply wants America to have things like free higher education, free healthcare and free child care programs like Denmark and Sweden. He also said he's proud to be the longest running Independent senator in United States history.
