Maybe this is the problem then? If you have less federal government control, and more state-level control then it wouldn't be as big of a deal if Trump is elected if you're a Californian. Likewise with a democratic candidate.

And the current setup actually works pretty well. You should get diminishing returns on popular vote in a republic. Otherwise you have some areas that dominate others instead of a balance. In other words, you don't punish people/states that are not highly populated. It may not have worked out for us this time around, but it's more fair. If you want a different system, then abolish the Republic and the States.
