Trump's own commission on voter fraud quickly folded with zero evidence of voter fraud.
CA & NY aren't the only States where anyone voted Hillary. That's just very silly.

The EC was created because the Founding Fathers believed average voters (who initially were to be only land owning Protestant men of means) were just too stupid to vote wisely. It was to prevent the election of a populist with autocratic aspirations who might destroy what they had wrought, you know, like a Trump.
Appeasing States with lower pops was a secondary issue, a concession to them.
In all but 2 States, the EC is winner take all. So even votes against the winning presidential candidate within a State are awarded to them. While it various, basically half the voters within these States had their choice negated. So on a State level, the EC does what you claim it counters on a Federal level, only worse, since the popular votes are not reassigned to the winner.
