The DNC likes to front load southern states. Their democratic primary voters are mostly older African Americans who typically vote for more moderate candidates
Although, this does have a point. Democrats can’t win the presidency without high black turnout in Milwaukee, Detroit, and Philadelphia. Allowing someone like Pete Buttigieg to win the nomination without black support would doom chances in a general election.
Hence I support a national primary day where every state voted. Candidates would have to balance every region
How would you prevent a fifty-state same-day primary from overwhelmingly favoring candidates with high nationwide name recognition and lots of cash? Obama would've probably failed to get the nomination in '08 under this system.
(Btw, I’m extremely skeptical Obama wouldn’t be the nominee in 2008. The party fell in love with him after he gave the keynote address at the 2004 DNC. He only ran because
Chuck Schumer and Harry Reid, the two most powerful senate democrats, went to his office and begged him to run against Hillary, their close congressional ally)
Obama barely won the nomination in 2008 to begin with and his strategy relied on the nomination relied on dominating the caucuses which were far more prevalent then they are today as he didn’t really do good in the larger state primaries . Obama’s nomination was very much a victory of playing the delegate math game In a brilliant fashion and he just would not be able to do that if there was a national one day primary .
In fact he may have not won the nomination if it was held under 2020 rules which had far less caucuses . If you want to see how much caucuses benefited him just look at the 2008 Texas primary Vs caucus results and you will see that
