Actually, it was ~30% of the voting population.

According to Wikipedia[0]:

Trump/Vance received 77,302,580 votes (49.8% of votes cast)

Harris/Walz received 75,017,613 votes (48.3% of votes cast)

Total votes cast: 152,320,193.

Those in the US eligible to vote[1]: ~250-260 million.

77,302,580/250,000,000 == ~0.3 or 30%.

That's worse, though. It implies that 40% of the "electorate" was (in some combination) either prevented from voting or not bothered enough by the difference between plausible electoral outcomes to actually try to influence said outcome.
