What about the argument that Obama and Biden wouldn't have won their elections? Lesser known candidates won't have time to make a name for themselves.
Hillary wouldn't beat Obama and Sanders probably would've won the primaries and most likely would've been beaten by Trump.
All fifty states should have their primaries on the same day. This isn't the 1850s and candidates don't have to campaign by train anymore. The only reason the tiered schedule persists is that it makes make huge amounts of money for the early states. We've tricked ourselves into believing this system produces a better result. It doesn't. End it.
