I forget the exact numbers but there are just a shade under 20,000 state and federal elected officials in the county, and right now I think the Dems have something like 80 more positions than the GOP - out of 20,000.
I really don't see this as relevant -- at all, in fact. Some states have larger legislatures than others. Some states elect more executive positions than others.
The issue that this topic brought up was that the sunbelt is growing at a faster pace than the Democratic states in the northeast. Thus, that gives the GOP more EVs as time goes on, and more representatives.
My point, perhaps poorly expressed, is that the two parties are at a point very very close to parity right now. The fact that they are so close, also means they will likely stay close for a while also.
An imperfect anaology to this is a college with a truly fantastic football program that is alway in the hunt for the National championship....
All the really great High school football players want to go to this school when they get to college... which means they tend to STAY at the top.
The GOP and Dems are so close at all levels that they also also getting very similar shares of the :high draft choices" in terms of new faces and new organization. This parity goes all the way down too. The DEms have (if my memory is correct) 99xx elected state officials, while the GOP has 98xx.... parity within a % or so.
