No...what is it?
First, let me say I hate the system we have now, and I fully feel you on the frustration. But there are better solutions - and frankly - there’s already talk of scrapping the Iowa/NH start for next cycle.....which I’ve been in favor of for a LONG time.
But your solution would fail as a test of time measure....and it would greatly magnify the power of those who entered the process with a lot of name ID and money.
Now perhaps social media and cable and talk radio and so on are making this less the case.....but there are unintended consequences with one national primary day.
