Hillary needs 37% of the remaining delegates . . . and to delay her felony indictment.
She'll need a lot more than that. You must be adding super delegates to your count. Remember that super delegates can change their vote. Back in 2008, it looked like the super delegates were going to allow her to prevail over Obama. It wasn't until the end of May and the beginning of June that the super delegates began to switch from Shrillary to Obama, forcing her to finally concede. But she was fully expecting to get coronated at the convention despite having been beaten by Obama in most of the primaries.
The democrats have better candidates than Hillary and Bernie, but they are counting on Hillary getting the nomination and losing the general. That way they are done with her and Obama. Then they can start to repair some of the damage Hillary and Obama have done to their party.
