Sanders Is Running Out of Open Primaries

First Read: “There’s another potential problem for Sanders as the Democratic contest heads into New York, which is Clinton’s home state but also where Sanders grew up: New York is a closed primary, which means that the independents that he won 72%-28% in Wisconsin won’t be able to vote. And the deadline to register as a New York Democrat ended on March 25. Of the 16 Democratic remaining primaries, just three are completely open contests.”
