The gerrymandered system with even more party control is not the system that has been in place for anywhere near that amount of that time.
The parties in place dont have that kind of history either.
Our voting laws are different, even non-white men can vote now! (though they are disenfranchised as much as possible.)
Basically, the system is constantly in flux, ad yes, we get to complain about it all we want and change it (again.)
There are maybe two states that have large electoral college districts that could be impacted by it, but they are irrelevant in the larger picture.
But changing it requires changing the Constitution, which requires a supermajority of state legislatures—and the electoral college shifts power from citizens and the federal government to states.
This hack lowers the barrier, but not by enough, at least yet.
