It would absolutely help. We humans divide ourselves politically into groups. Washington's lament of the rise of factions was noble but naive. We need a voting system that enables political parties in the United States to rise and fall. People need more than two choices. I believe changing our electoral systems for all levels of government to something like Ranked Choice or Approval (or multi-member systems) is the defining institutional change needed of our time. It won't directly solve every first-order issue directly (taxation, spending, social safety nets, military, scope of government, etc). It will, however, allow us to break ourselves out into more representative groups of ideas. It will force politicians and parties to compete on the merits of their own ideas rather than "not the other party". It will allow voters to vote for ideas rather than against others. The concept of "lesser evil" will be weakened if not broken. I believe it is critical for the culture and political survival of the United States to move away from first-past-the-post voting.
