Sanders also bested Clinton in head-to-head polls against the remaining Republican candidates, beating Donald Trump by 24 points, Ted Cruz by 12 points, and Ohio Gov. John Kasich by 4 points. In comparison, Clinton won against Trump by 18 points, and Cruz by 9 points — but lost to Kasich by 4 points.
The next primary is Wisconsin’s on April 5, where Sanders is likely to do well in the delegate-rich city of Madison, even if he does not win the entire state. The latest poll in the state, conducted by Emerson College, also has Clinton and Sanders neck-and-neck, with Clinton leading by 6 points with a 5% margin of error.
At a rally in California on Wednesday, Sanders told his supporters that if there is a large turnout, he can win the state, and if he wins by a large margin, "we are going together to the White House."
Still, Clinton maintains a massive delegate lead on Sanders especially when Super Delegates are factored in, though Super Delegates do not vote until the convention in July and are not bound to stay with the candidate to whom they’ve pledged loyalty.
