Can't use RANKED-CHOICE voting for President, Vice President, Representatives or Senators unless the Constitution is changed.
There would have to be some compelling reason why a different system is needed.
Ranked-Choice might be useful for choosing your favorite band, food or car, but it's not suitable for electing our leadership.
This is not a dog race where you bet win, place or show. This is a race to put someone in office you actually want. If your #1 fails to win, would you really be happy your #2 crossed the finish line?
People today are polarized, and in spite of arguments to the contrary, ranked-choice will not reduce the polarization. If you don't like Candidate "D", you'll put Candidates "A", "B", and "C" as your top 3 choice to try and keep "D" out. The difference is there's now a chance to defeat "D" if your #2 gets more votes than "A" or "D".
If preventing someone from winning is how you define winning, then maybe this system is what you're looking for -- more of a chance you'll get your wish. Just remember -- the other party can use the same system against your guy, too.
In Presidential races, the winner must get a majority of votes. If no candidates makes that threshold, the race is decided by Congress.
Most state and local races are by plurality -- the one with the most votes wins regardless of whether anyone received a majority of votes.
The reason there is a difference is a plurality is based on the total number of people voting. That number changes election to election. The general election is based on electoral votes, the total of which is decided by the number and population of states. That keeps the elections from being decided every 4 years by a few states having the majority of residents.
There's little that can be done to fix the polarization of our political system. Pushing a new method of voting is just another way of trying to destroy the electoral college system. There is already an effort to get states to swing their electoral votes to whoever wins the popular vote.
