Think about it like this:
Imagine that among the 50 states, two were entirely industrial and the other 48 are agrarian. If two candidates ran for president and one was hardcore set on making the entire country a technological wasteland and eliminating the agrarian lifestyle and economy, he could win if Texas and California [[for example) turned out in sufficient numbers and the others [[for whatever reason) had low turnout, since they are the heaviest populated states. Consequently, two states would dominate the election, so the candidates would only need to cater to their needs instead of caring about the entire country. The end result would be that they would control the country instead of having candidates appeal to each state as they do now.

It's imperfect, but it has roots in fair representation. Besides, it's water under the bridge at this point. Our hawkish, pro-Russia, racist, idiot of a president-elect has already been given his assignment by the voters. Let's see if they want what they got.
