That's just not true though in regards to the outcome of the presidential election.
Elections are pretty much decided by voters in Ohio and Florida.
Look at ad spending by state. Biden and Trump will ignore more states than they invest in because the states are not competitive. That's what the founders wanted?
and for context, I expect democrats will be able to flip Texas to blue within the near future.
If that happens, they can lose PA, OH, MI, WI and Florida and still win.
The concept made sense for a period of time but has outlived its usefulness.
