> urban voters are currently disenfranchised

That's an odd way to complain about not being utterly dominant.

> We have Trump because the system discriminates against urban voters, i.e. currently the majority is being damned.

That's a pretty myopic read of the situation, and not very valuable. The solution to something like Trump is not to create a permanently disenfranchised and forgotten hinterland, which really seems like your desired outcome.
