Regardless of who came up with it, we definitely need to get rid of it. My issue with a district system is gerrymandering. That already causes issues with our current system, I couldn't imagine how terrible it would be in a district-driven system.
Even if you want to get rid of it, many people in the USA don't want to get rid of our system. Nate Silver did a piece on it. Pretty much, even if all the Blue States voted for the National Popular Vote Interstate Compact (Which means who ever got the most votes Nationwide, would become President of the USA), you would have to convince Purple and Red States to vote for it. However, Purple States are unlikely to vote for it because they have a large influence over who becomes the next President of the USA.
On the other hand, you would have to convince Red States to join with it, but that has its own set of problems. Nate Silver wrote his piece before 2016, but a decent chunk of Republican voters want to keep our current system. Go onto any Facebook post about changing our system, and it turns into, "We should not change it, because that means California and New York will pick the next President," or, "Democrats are crying babies who want to change the system when their candidate didn't win."
I'm not saying it will never be fixed, but we need to fix things at the State level. Look at Maine, it changed how it will elect its Governor, so anything is possible.
"Republicans have fought hard to block the new system in court, saying Democrats are pushing the measure to ensure that a conservative governor can't get elected to office. And even Democrats in other states have opposed a ranked-choice system. California Gov. Jerry Brown (D) blocked its wider use, saying ranked-choice voting is 'overly complicated and confusing' and 'deprives voters of genuinely informed choice.'
'I think you outright win these things. With ranked choice, you could be No. 2 and win. I don't think that makes sense in an office where any degree of strength is required," Sen. Dianne Feinstein (D-Calif.) told HuffPost. ' "
Of course, getting Democrats to get onboard isn't easy either.
