We are sick of it, but despite being somewhat of a democracy, we have no real power in this two party, first past the post system when both parties always run establishment candidates, aka, billionaire thieves gang members.
When is the last time the Democrats ran a billionaire?
There are more offices than just the president. Third parties often win in local elections (I don't know numbers, I doubt more than 5%). They win in state elections from time to time as well. If you get involved you can build a third party until it cannot be ignored.
