That's a complaint which is not particular to rural voters though right? The same can be said of the impoverished urban masses gripped by hopelessness and drug activity. Or the impoverished suburban masses gripped by hopelessness and an opioid epidemic.
Many voters all over the US "... feel alienated from the actual politicians they're able to pick..."
Closing the chasm between leaders and those being led is an age old problem. It's a problem that was likely present in every great civilization.
And the democratic principle would be more perfectly approached: At the moment, there's 436 democratically allocated seats in presidential elections, versus 102 non-democratically allocated seats. With a doubled congress, it would be more like 872 give-or-take versus 102 (the exact number will depend on how many congress seats Wyoming earns, as this affects the number of college seats DC receives). This benefits urban residents most clearly.
>This benefits urban residents most clearly.
Yeah it benefits urban residents at the expense of rural residents. There's no way you can claim it would make everyone better off, it reduces rural voting power in presidential elections.
