One of the most prominent argument in favor of keeping our current electoral system in place is that it keeps small states from becoming ignored. But in reality, the Electoral College is not doing much to promote the relevance of small states. From the New York Times:
The Electoral College’s small-state bias had essentially nothing to do with Donald J. Trump’s victory. In fact, he won seven of the 10 largest states, and Hillary Clinton won seven of the 12 smallest states.
Over all, the Electoral College’s bias toward small states probably cost her a net of four votes — essentially nothing.
If there is a benefit to protecting small states, the Electoral College is not doing a great job of providing it. Big states can dominate small ones under the system, and they have done so at times.
