Well direct voting for one. I can understand why so many Americans just don't vote now, following this election.
how?
The USA is not one State, it is Union of States a bit like the European Union is not one State. The USA a Federation of Individual States.
Direct one person one vote for the president would completely change the political structure of the country handing all the power of the Federales, via the swamp monsters of DC to the populous coastal states. Democracy is the tyranny of the majority over minorities, actually it is the tyranny of a vocal minority pretending to represent the majority over all others. Which is why there are checks and balances, power was divided between the branches of government, this division of power in the USA has been broken by the continuous expansion executive branch power but there are still some checks and balances left.
The electoral college could be abolished but then the USA is no longer a Constitutional Republic or a Union of States and the smaller states would ultimately secede from the Union, Otherwise the population of the smaller states would have no voice at all, their voice drowned out by the clamor of the multitudinous hordes in the coastal states.
to quote creepy Joe
Democracy is sometimes messy, so sometimes it requires a little patience. But that patience has been rewarded now for more than 240 years with a system of governance that has been the envy of the world.
240 years with only a few minor issues: one civil war, at least 3 stolen presdiential elections Kennedy, LBJ, Bush routine disenfranchisement of voters, The world is indeed truly envious of the uncallenged ease with which American poiliticans spew out this crap.
Eventually, if they survive, people will come to realise that less government not ever expanding government is the solution to the problems of over reliance on government. These changes tend to be brutal. It is still not too late to meet in the middle.
