While I'm glad this came out now, really credit should be going to David Daley who detailed this in Ratf**cked, which was published in July of 2016.
> think of the gerrymandering that allowed after the 2010 census
would you like to know more?
I mean, it's not supposed to be representative, but it's also not supposed to [be subjected to targeted disenfranchisement and suppression tactics[(https://www.amazon.com/Ratf-ked-Your-Doesnt-Count-ebook/dp/B016APOCRU/ref=sr_1_1?dchild=1&keywords=ratfucked&qid=1603715370&sr=8-1) (AKA, cheating).
I highly suggest you review some information regarding this system and the pros / cons to it.
Namely, you should look at the history and current struggle of voting rights and gerrymandering. NC is in the news right now for exactly these reasons. RatF**ked: Why your vote doesn't count and Give Us The Ballot are two relatively recent books that describe a lot of the issues voter equality faces. The reality here is that the GOP is gaming the system while they have the ability to, in order to keep that ability without evolving. So, to make this change like you suggest which is supposed to be easy, it is an uphill battle where Democrats have to essentially win elections that have been heavily slanted towards the other side. If they do win, they need support from the rest of the governing body at that level which is struggling from the same problem, as you can see with KY. Despite Beshear's victory, the GOP is now trying to strip him of a lot of governing powers to limit effectiveness.
As a second point here, the government is not designed for rapid change. The idea that it is difficult to do so is an intended outcome; hypothetically, the majority of proposals will get shot down and only the "best" make it through. Constitutional amendments require time and lots of energy to implement, and as such, the removal of the electoral college is going to be extremely difficult. And to an extent, this is a good thing. Think of how easy it would be to strip voter rights, etc, if you could easily change the Constitution. The unfortunate reality is that we live in an era of instant gratification where people want change, want it now, and forget about it 10 minutes later. This will take time, and people have to keep at it for years, gradually taking two steps forward and one step back.
