The problem with your statement is it ignores "winner take all" in the EC. That invalidates and marginalizes that part of a state whose wishes are for another candidate than the one who won the state overall.
There are many problems with our election system that are intentionally designed to disenfranchise huge portions of the population. That is why you have such a low voter turnout in election in the US.
The biggest elephant in the room has nothing to do with the structure of the election system and has been ignored in this topic. Namely, the baby boomers that are retiring with nothing better to do than visit the graves of their dead friends and family and vote. As people grow older, they tend to get to be more crotchety "get off my lawn" types (read conservative). The US will swing much more red as more and more of them retire.
