The DNC had better stop trying to foreclose the primary in favor of Clinton and go all out to make Sanders the nominee.
Donald Trump holds a 15-point lead over Ted Cruz in the potentially decisive Indiana primary in a new NBC News/Wall Street Journal/Marist poll.
In a hypothetical general-election matchup, Trump is ahead of Clinton by seven points among registered voters in this traditionally Republican state, 48 percent to 41 percent.
But Trump's lead is just one point when matched up against Bernie Sanders, 47 percent to 46 percent.
Meanwhile, Cruz also is ahead of Clinton by seven points (50 percent to 43 percent), while Kasich leads the former secretary of state by 19 (56 percent to 37 percent).
Kasich beats Sanders by one point (47 percent to 46 percent), but Sanders leads Cruz by three (48 percent to 45 percent).
