All the elections in which the popular vote winner was not the Electoral College winner deserve some mind of asterisk.
Disagree. The electoral college is the rule, so the candidates follow an operation designed to take the electoral vote.
Say the rule in 2000 was that the popular vote determined the winner. You think Bush wouldn’t have campaigned differently, visiting places like California, Texas, and New York? You think his people wouldn’t have placed money and TV ads in those places? And if he did, how can you be so sure that he would have still lost the popular vote?
Basically, they lost the popular vote because they didn’t chase the popular vote. Had they chased it, it’s possible they would have taken it.
