A question that has long been standing in my mind is whether the Electoral College is constitutional.
Republicans in California, or Democrats in Texas, for that matter, actually do not have a say in the national presidential election. In essence, the electoral college system allows a simple majority in the popular vote to essentially vote in place of the losing party as well.
Although AFAIK there is no part of the Constitution where unequal voting is barred, it does seem to contradict the idea of equality present in the current Constitution. Thus the question would be, does it violate the 9th Amendment?
