All this is leading up to is having one national primary day election held before the general election in Nov.
Which may or may not be good.
I think it is bad because it requires a lot more money to campaign across the whole country at the same time. We need to be going in the other direction. There are a lot of great candidates that can't possibly win because they don't have any corporate cronies backing them as it is. Doing a few states at a time lowers the bar and allows people to making a good showing in some early states to build some momentum and increase their fundraising so they can compete in the other states.
I don't think it is right that the same states always go first though. In my opinion, states that want to go early should apply and then they rotate through them. I suppose some states are perfectly happy not going first, so they just wouldn't apply.
