The phrase 'hordes of millions' is important to take note of... By the most liberal estimate I saw, there were a few hundred people that attended these protests, the largest single one had a few thousand, overall we can say 10 to 15k across the whole country. That's 0.0002% of Trump's voter base, and 0.00005% of the American population.
