I think you need isolate the noisiest extremes of the left and right and find that silent, moderately conservative majority of the population that wants a small, reasonable government to work. You're absolutely right that it won't be easy and is a bit farfetched, but you have to at least try. Schumer won't be the champion of this, nor will Biden or McConnell or Pelosi. But you have to hope that eventually enough reasonable people in the next generation will see this current system isn't working as well as it can be and needs a major tune up.
