Way more than half the country was disenfranchised in the last election. Best case scenario (and very unlikely scenario): blue sweep in the next elections and then massive electoral reform.
Electoral reform is really hard for parties just voted in by that election system. Suddenly they see the good in that which they had previously seen as bad.
The USA has about 342 million people, and over 18% of them are age 14 or younger (https://en.wikipedia.org/wiki/Demographics_of_the_United_Sta...) and at least some of them are 15-17 (citation needed). So clearly, doing some arithmetic, there are fewer than 304 million adults.
Not only was "half the country" not "disenfranchised", literally a majority of adults actually voted (and this is not even considering that not all adults were statutorily allowed to vote in the first place).
If that is what you're referring to, then it's nothing particular to Trump. Not all of it is even particular to the US; for example, Canadian electoral "ridings" function like single-EV states.
No dispute there. It's just a terrible system that has no reason to exist. No telling what turnout would be if more of the country new their vote might matter.
