Money In Politics
Two Party System
Gerrymandering
Electoral College
The four horsemen of a Democratic apocalypse.
If we could fix just one of those four issues, things would gradually start to get better. But the politicians in Washington don't have the political will or desire to do so, because removing any one of them naturally limits their power and authority.
I don't disagree, but the problem stems from neither party being motivated to be anything more than ideologically different from one another, and the system being designed on purpose to squash a viable 3rd party from ever emerging. If we instead had a parliamentary system and did away with FPTP voting, we could have more coalition building around issues rather than feeling like we have no choice but to select what we deem to be the lesser of two evils, and political parties would be forced to fix issues rather than just campaign on them.
