Health insurance industry stocks surged Wednesday, one day after Joe Biden won 10 of the 14 states that voted on Super Tuesday. Biden opposes Senator Sanders’s Medicare for All legislation, which would replace private insurance companies with a single-payer plan to cover all Americans.

In Vermont, Senator Sanders acknowledged Wednesday his campaign needs to turn out more young voters if he’s to win the nomination. Sanders said he looks forward to debating Joe Biden on March 15.

Sen. Bernie Sanders: “Joe is running a campaign which is obviously heavily supported by the corporate establishment. At last count, he has received funding from at least 60 billionaires. Sixty billionaires. Our campaign has received more campaign contributions from more Americans, averaging $18.50, than any campaign in the history of our country at this point in time. So, what does it mean when you have a campaign which is funded very significantly by the wealthy and the powerful? Does anyone seriously believe that a president backed by the corporate world is going to bring about the changes in this country that working families and the middle class and lower-income people desperately need?”

The Washington Post is reporting top surrogates and allies of Senators Elizabeth Warren and Bernie Sanders are discussing ways for their two camps to unite and push a common agenda, with the expectation that Warren will drop out of the race.

The next round of primaries is set for Tuesday, March 10, when voters go to the polls in Idaho, Michigan, Mississippi, Missouri, North Dakota and Washington. Nine percent of all pledged delegates will be up for grabs.
