Given how messy the future US presidential elections will be between Biden and Trump, I was thinking why don't American try to to inject more direct democracy in their system. Like do something similar Switzerland, but instead of cantons you have states. Like you need a majority of the people AND states to change the constitution, and any citizen can start gathering signatures for a referendum on either state or national level (and maybe also city/town level like in Switzerland for Gemeinde/Commune).

And ideally, the congress would appoint the president and vice-president, like in Switzerland where the Parliament appoints the Federal Council. So you don't have presidential elections that costs billions of $ where people from the whole country vote for one of two people. I always preferred the Swiss system because it makes it less about the individual itself, there is less peoplization. I find it crazy how American put so much power in just one person.

People would keep electing members of the Congress, and the Congress would then appoint the President and Vice President, or maybe they would just adopt a similar system with the Federal council. Like the Presidential Cabinet would become some kind of Federal Council, and the President would just become a honorary role without much power, like in Switzerland.

Why don't they try this ? This seems so much more efficient than the current system
