Eleven of 48 Senate Democrats have now decided to co-sponsor Sen. Bernie Sanders's single-payer health care bill — just two years after Sanders could find zero co-sponsors for his legislation.
The bulk of the Senate Democratic caucus has not yet come around to Sanders's Medicare-for-all bill, which is scheduled for release on Wednesday.
The majority of those backing Sanders's Medicare-for-all bill tend to hail from blue states or are rumored 2020 presidential candidates. Still, as Vox's Dylan Matthews has written, the endorsements are illustrative of a stunning shift among Democrats to embrace single-payer legislation — which was once circumscribed to the party's far-left fringe.

In late August, Sen. Kamala Harris (D-CA) became the first Senate Democrat to back Sanders's bill. She was quickly followed by Sens. Elizabeth Warren (D-MA), Sheldon Whitehouse (D-RI), and Kirsten Gillibrand (D-NY), as well as Cory Booker (D-NJ) and Brian Schatz (D-HI).
Sen. Tammy Baldwin (D-WI), who is up for reelection in 2018, became the first senator from a state won by Donald Trump in the general election to back the bill on Tuesday. (Though Wisconsin is a traditionally blue state that frequently elects Democrats.)
But several Senate Democrats have also said that they will not co-sponsor the legislation, and Senate Minority Leader Chuck Schumer has not formally stated a position on the bill.
