We may not have seen the last of Bernie Sanders on the presidential stage.

During an appearance on HBO’s “Real Time” Friday night, Sanders didn’t rule out a future presidential run when host Bill Maher suggested he could still mount a future campaign, even at his advanced age.

“Bill, I mean, thank you very much, but four years from now is a long time off from now,” Sanders replied, not exactly ruling out another presidential run. “My term ends in two years as a U.S. senator from Vermont. Everything being equal, I intend to run for re-election from Vermont, a state that I love very, very much.”

“But what I will tell you is whatever my political future may or may not be,” he went on, “I will be fighting as hard as I can to stand up for a declining middle class, to take on the grotesque levels of income and wealth inequality that we’re seeing right now, to demand that the United States join the rest of the industrialized world and guarantee health care to all people as a right, to make public colleges and universities in this country tuition-free. Those are issues that we have got to continue the fight for.”

Even now at 74, Sanders would have been the oldest person ever elected to the White House.

At 69 in 1980, Ronald Reagan was the oldest elected president in American history.
