"Clinton cut short her campaign in Wisconsin to concentrate on shoring up her home base. She kicked off her New York campaign with a rally atthe Apollo Theater in Harlem. She stumped at black churches in Brooklyn, where she talked about gun violence and accused Sanders of voting with the National Rifle Association. On Saturday, she attended an organizing event in Sunset Park, a heavily Hispanic part of Brooklyn, with Congresswoman Nydia Velázquez and the Puerto Rican-American singer Toby Love. If Clinton can get large numbers of Latino and African-American voters, as well as women over forty, to turn out, Sheinkopf told me, “she should swamp Bernie Sanders in New York City.”
Another factor playing into Clinton’s hands is that the primary is a closed one. In Wisconsin and other states with open primaries, Sanders drew in a lot of independent voters. But voting in New York will be restricted to registered Democrats, and the deadline for switching from independent to Democrat was last October, which means that some of Sanders’s supporters may not be able to vote."
