Something to keep in mind is that Trump's support, from voters, so far, is less than 50% of the people who voted in Republican primaries and caucuses. SOME, but I would think not all, of those people will vote for him if he gets the nomination. But there are a LOT of other people who won't. But, there's a chance that Clinton, if she's the nominee of the Democrats, is a polarizing enough individual that a lot of people won't want to vote for HER.....
I think we need to rethink the whole nominating process. Right now, it's totally up to the 2 major parties and they have some kind of odd and convoluted ways of doing things. I'm fine with them getting to pick THEIR nominee any way they want to, but we need to have a way to include people who don't belong to the 2 major parties in the process too. The parties can do what ever crazy and corrupt thing they want, but we need to find a way to get the will of the people into the process much much earlier, so we don't keep ending up choosing the lesser of 2 evils.
