D. An (slightly) alternate solution.
I like the fact that the presidential campaign is, in essence, fifty-one smaller campaigns. So, I don’t mind the theory behind the current set-up.
The one small change I would make is getting rid of the actual electors. Instead of electing a slate of electors, have each state count for a number of points (calculated the same way that the current Electoral Votes are calculated). The winner is the first candidate that gets a majority of the points.
What does this do? It gets rid of potential faithless electors (electors who vote for candidates other than those whom they are pledged to vote for).
