Sen. Bernie Sanders promised voters on Saturday "a real clash of ideas" should he and Hillary Clinton seek the presidential nomination in 2016.
"I happen to like and respect Hillary Clinton," the Vermont Independent told Steve Kornacki on
MSNBC, "but I suspect on issues like massive investments in infrastructure, on real tax reform, on the need to deal in a very bold way with the planetary crisis of climate change, with the transpacific partnership, I suspect we will have some real differences."
Sanders, 73, did not say whether he would mount a candidacy as a Democrat or Independent.
He has been an Independent since 1979, though he caucuses with the Democrats.
Clinton, 67, the former secretary of state, is expected to make a decision in the coming months.
According to Sanders, his agenda would primarily focus on income inequality. The United States has "more wealth and income inequality" since 1929, he said, and "the middle class is continuing its 40-year decline.
"We need a political revolution in this country," he told MSNBC. "We need to get people once again actively involved in the political process and take on the people who have the real power in America."
He argued for improving the nation's "crumbling" infrastructure, as well as creating a living wage and a "national health care program that guarantees health care to all of our people."
Sanders said his agenda could win despite a GOP Congress if progressive candidates can rally enough Americans, "giving the Republicans an offer they can’t refuse, yes, we can be successful.
"We may not get everything we want. I think we can push the Republicans to raise the minimum wage a lot higher than it is right now," he said.
