I believe it is up to the states how they elect representatives. It's a little harder with the presidency, because of the electoral college (a state may be at a disadvantage if they used approval while other states use plurality...it does not good to pick a middle ground candidate if they can't actually win). However, changing the way we elect representatives/senators would go a long way. https://www.electionscience.org/ces-updates/making-approval-voting-a-reality-in-us-elections/ https://www.electionscience.org/ces-updates/making-approval-...
