Well, yeah... that’s true... but lots of people live in population centers, by definition. Doesn’t having a lot of people mean you should get more of a say?
As it stands, presidential candidates pretty much skip our country’s cities (NYC, SF, LA, Chicago, Houston, Dallas) for all but fundraising purposes because they are located in states that are not battlegrounds.
If Republicans had to really contest these big cities, and couldn’t just coast off of the battleground state votes, you bet the GOP’s platform would modernize in a big hurry.
