Reagan did not win in an complete and utter dismantling of Carter either. That was true electorally. The EC is designed to create a clear winner. Popular vote wise he won by 10%'ish. That's more than Obama and yet that was considered a landslide. There's been other elections where the popular vote was as much as 60% and some in the 30% range.
“Experience should teach us to be most on our guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.” — James Madison
