Sen. Bernie Sanders (I., Vt.) said Wednesday he will continue in the Democratic presidential primary even as Joe Biden expands his delegate lead.
"We are strongly winning in two enormously important areas which will determine the future of our country," Sanders said during a press conference in Burlington, Vt. "Poll after poll, including exit polls, show that a strong majority of the American people support our progressive agenda."
Sanders argued that "millions" of Biden voters agree with Sanders's agenda but consider Biden a better bet to beat President Donald Trump.
"While our campaign has won the ideological debate, we are losing the debate over electability," Sanders said.
He also celebrated how his campaign has also been winning "the generational" debate.
"It is not just the ideological debate that our progressive movement is winning," Sanders said. "We are winning the generational debate. While Joe Biden continues to do very well with older Americans, especially those people over 65, our campaign continues to win the vast majority of the votes of younger people."
Sanders said young voters "represent the future of our country" and the Democratic establishment must address the issues they care about.
"You cannot simply be satisfied by winning the votes of people who are older," he said.
He reiterated key points from his platform while challenging Biden to speak to the same issues moving forward.
Sanders also said he looks forward to debating Biden on Sunday, March 15. Some Biden supporters and members of the media have floated the idea of the debate not taking place, including House Majority Whip James Clyburn (D., S.C.), whose endorsement powered Biden's comeback performance in South Carolina.
