I think that some of the problems with the EC would go away if the number of electors/House seats was updated to match current U.S. demographics. The last time that was changed was in the 1930s, if I recall correctly. In the first United States Congress, there were about 65 thousand Americans per representative. Nowadays, that ratio is closer to 760 thousand Americans per representative.

Unfortunately, that kind of rebalancing has zero political support. The National Popular Vote Interstate Compact, while not as good a solution in my opinion as it doesn't fix the underlying problems with citizen representation, is probably more politically feasible in terms of fixing presidential elections.
