—Rig the system and not too far in the future...—
I would not apply the word “rig” to this. It actually makes it more fair. It is appalling that one guy can “slightly” win a ton of states and, therefore win all of their votes, while the other can win far more votes, but they are lumped in only a few states, so he ends up losing. I like representative government to be a little more “local” than that.
The proposal is a method of nullifying the Constitution. If change is needed - change the Constitution all fair and square and above-board.
It makes sure that one area of the state doesn't consistently dominate every election, particularly when it is an area which is prone to fraud and fake votes as is the case in Pennsylvania.
It also equalizes votes so that every voter is picking three electors. Seven of Pennsylvania's congressional districts are highly competitive. Another five are somewhat competitive. Add the two at large votes and candidates will be able to compete for 9-14 electoral votes. They will just have to do it throughout the state rather than in the 1 or 2 largest media markets.
The RATs have been pushing their stupid National Popular Vote plan since the 2000 election. This is a logical counter.
