There’s a few pretty cool advantages to the Electorial College that don’t even really need to get into the whole issue of states rights.
One of those advantages is in how it relates to close elections. What if we had a national election where the top two candidates were within a couple tenths of a point? Look at the mess we had in Florida in 2000 and multiply that by 50. I can’t even begin to imagine how such a recount could be done in a timely fashion without countless objections to different standards and all of that. To counter that, it would likely require very specific and strict national voting guidelines regarding how votes are done (mechanical, electronic, manual), how they’re counted and all of that. How might those national guidelines align with various other guidelines for handling state and local elections?
It forces other issues that might otherwise be ignored to be considered. If we had a national popular vote, generally the only issues that will need to be addressed are the issues that most affect the prime demographics, issues related to taxes, entitlements, foreign relations, all of that. We could very well have elections that ignore significant demographics and other major issues. For instance, Virginia is a swing state, and some of the major issues here are defense spending, transportation, and energy. Besides just benefitting Virginians by getting issues we care about addressed, it helps all of the country by getting a broader picture of the candidate and those issues affect a lot of other areas too. Without being forced to focus on those issues, I could very well see the presidential elections focused almost entirely on taxes, health care, and job creation.
Electoral College will also generally increase the value of one’s vote. There was a good thread about this, I think 2 years ago, but I’m too lazy to look it up. Basically, in a national election, I’m one vote in 360M votes. Whereas, in my state, I’m in a smaller pool, so I have a greater chance of affecting the Electoral Votes for my state and, thus, a greater chance of having some impact on the total election. Of course, in practice one might argue that this isn’t true in some states that are pretty solidly Republican or Democratic, but that’s not really any different than how it would be in a national election.
That’s not to say it doesn’t have it’s issues. It certainly does confuse a lot of people. There’s always the issue of unfaithful electors. I’m just not sure that the issues it has outweigh the benefits, including the issues of states’ rights, to make the costs of switching worthwhile.
