The New York City Daily News, second only to the old Lady, New York Times in its liberal bias, reports that "hundreds" of anti-Trump protestors showed up to demand that science bow to politics yesterday.

It's possible that many millions of New Yorkers who would otherwise have attended New York's party donned their pussy hats and diverted to Washington instead, but I suspect the minuscule turnout was a true reflection of the size of the Democratic base on this issue.
