When I was young, I didn't understand why the popular vote didn't really count during these elections, since this is supposed to be a democracy. Well now I know why. The founding fathers created the electoral college in the off chance that the general population goes full retard and vote based purely on emotion and not facts and policy. I see this happening right now.
A lot of these polls, from what I know, are based on mostly internet activity, and as we all know, most who have a vocal voice on the internet tend to be racist. A lot of comments on news articles and what not all seem pretty racist to me. In other forums around the net, depending on the subject matter of the forum, you tend to find more moderate people who are against Trump's extreme views.
Now I'm kind of glad the electoral college exists. Imagine a country where the majority of voters are white nationalists and racists. We'll pretty much devolve as a country back to civil rights movement times.
