Hilary still needs 824 delegates to win (what she's won so far + the superdelegates she has, subtracted from 2383).
The Donald still needs 556 delegates to win (what he's won so far + 3 superdelegates for each of the 20 states he's won, subtracted from 1237).
At this point, I think that The Donald will be confirmed as the Republican candidate before Hilary will be confirmed as the Democrat candidate.
The Donald is already able to eliminate potential running mates - Alaska for instance wasn't won by Trump, which means Palin won't be on his short list. That actually breaks my heart because the selection of Palin would have guaranteed Trump's lose in the General Election. If the numbers on June 7 are such that New Jersey delivers the final delegates that Trump needs, then Chris Christie has a good shot at being on the ticket. If Trump already has enough delegates before June 7, his running mate will be who was able to deliver for him.
Hopefully this list of remaining primaries will paste properly
