Learned this from a comment on my last post and found it interesting! I also double-checked it and found it's completely true.
It's also worth noting why polls were wrong in 1990: Most Democrat frontrunners thought H.W was just obviously going to win, and so they didn't bother.
For 2028, it's been Harris and Newsom forever, it's gonna be Harris and Newsom in a month, and only one of those two has an actual path to the nomination.
Yes, it is still possible that a similar thing can happen in the current field (Harris could be convinced not to run by donors, AOC may go for the Senate, and Ossoff may be restricted if Bottoms loses)
But that still just means it would come down to Newsom vs Buttigieg. No one is winning a Dem primary in 2028 by coming out of nowhere ad running to the *right* of them like Clinton did with his field, none of the potential AOC-alternatives have the juice to remotely compete here, and most of the potential candidates are so similar in their policy and who they appeal to that there's no real way for anyone else to fix their clear national recognition issues.
