Even if it ends 58-42 for Sanders it's a YUUUUGE improvement for Clinton compared to her 68-32 drubbing eight years ago. Both Nate Cohn and Harry Enten said it was a bad night for Sanders because he needed much bigger margins in two such friendly states and that he has fallen further behind when it comes to delegate math.
Let's just hope that when Clinton becomes head of the party she pushes for the abolishment of caucuses. Today was just another example of how ridiculous and undemocratic this system is.
I agree that Sanders is almost certainly going to lose the nomination, but Sanders is not Obama. Obama is not Sanders. They appeal to very different sections of the electorate, with some overlap.
