As far as predictions go, the only real question in my mind is if Trump will be able to get the delegates for a first ballot win. Trump will almost certainly win the popular vote, and if convention tomfoolery results in a different candidate being the Republican nominee then I think it will marginalize millions of Republicans.
I don't see the math working for Sanders. The democrats have no winner take all primaries, and I don't see him taking the 75ish% of the remaining delegates he would need to offset Hillary's super delegate advantage. I would be surprised if he beat her in the popular vote.
Sanders having a third or more of the delegates going into the convention will have an effect on the general election though. You will see the Democratic platform shift to the left. This would allow a nominee Trump to take the center, while discussing how Hillary has spent decades covering up her husbands rapes.
If Trump wins the nomination I think he is the next president. Any other Republican and I think Clinton will take it. Oh well. At least we know we wont get another Bush.
