Hillary got 2.9million more votes than the Donald. Please explain how a large percentage rejected her.

The Electoral College was not written for rural state and small pop they didn't exist then.

"James Madison responded that such a system would prove unacceptable to the South: “The right of suffrage was much more diffusive [i.e., extensive] in the Northern than the Southern States; and the latter could have no influence in the election on the score of Negroes.” In other words, in a direct election system, the North would outnumber the South, whose many slaves (more than half a million in all) of course could not vote. But the Electoral College—a prototype of which Madison proposed in this same speech—instead let each southern state count its slaves, albeit with a two-fifths discount, in computing its share of the overall count."

This is not about knowing better or other states ruling each other. People in California are Americans too, why do you not want their votes to count?
