no, because we should have it be nationwide, all at once.
Just because that is the logical conclusion to a nationwide trend as states front-load their primaries doesn't make it any better of an idea. Front-loading is a problem, and it needs to be fixed, not institutionalized. Are you truly not concerned that a nationwide primary will advantage only those candidates with the money and resources to compete on a national scale? Do we really want only billionaires and millionaires to compete for the nomination? Because that is exactly what this will lead to -the selling of the Democratic Party presidential nomination to the highest bidder.
That's already the way it is.
No, it's not. Otherwise, we'd be looking at Michael Bloomberg as the front-runner.
The last four competitive primary contests (2020 DEM, 2016 DEM, 2016 GOP, 2012 DEM) were all won by the national frontrunner pre-Iowa anyway and in most of the cycles before that, the well-funded establishment favorite won. Having a staggered primary just serves to create a prolonged and nasty process to get the result we were likely going to get anyway.
