There are plenty of things to dislike out about current system. I personally would be chary about making large changes that could have unintended consequences, and obviously one can propose all sorts of things here as hypotheticals, fine with me.
I know poll after poll for example shows the voters would prefer a direct popular vote for Presidents. That doesn't necessarily mean it would be a good idea (or not). And there is a Compact of the States in progress, sort of, that would make that happen without an Amendment.
I suspect if Democrats benefitted more often from the EC, they'd be for retaining it, and vice versa.
