I think voters should petition their local officials to change their local election systems to use some sort of proportional voting. Then we’ll get better local officials and we can keep pushing this system to higher levels.
I don’t like NPV. I wrote about that in response to someone else, but in short, it’s the same mentality as allocating all electors to someone who wins only a portion of the vote, which is inherently flawed. It’s better than what we have now, but it’s a hard sell because people never want their vote to go to a candidate they didn’t support, so there will always be states that rightly don’t support it.
