Seems you’re getting lost in the details.
My point wasn’t to play a game of “stump the chump;” it was to point out that there is already a process in place for getting this fixed.
The details of that process can be found at https://www.archives.gov/federal-register/constitution, for those who want to fix the problem instead of whining about how the system is rigged.
You could also potentially sue the states under the theory that “winner take all” violates equal protection guarantees. The Constitution does not specify how states must elect their electors, so there’s no federal mandate for “winner take all.”
