I’m not sure that’s the reason why it’s only worth campaigning in Georgia, Wisconsin, Arizona and some other states during presidential elections.

Also it is the system that was designed over 100-200 years ago. The problem is the lack of meaningful reform because the people in power are there only because of the current system.

That’s the reason why is it so hard to change electoral system without some external/internal shock. And “unfortunately” US has been way too stable politically during the 20th century compared to most other countries.
