It's not surprising that "the most unpopular new president in modern times" is generating daily protests, including a vow to ensure rallies follow him wherever he goes. The remarkable thing is how many people show up at these rallies--three times as many showed in Washington for the Women's March as attended his inauguration (and 2.5 million joined them around the world). Of course, numbers can always be questioned but with the president making such a big issue out of them, people seem to be more meticulous in their counting.
These photos are from a protest and march against Trump's executive order banning refugees and travelers from seven Muslim-dominant countries. The march went from Battery Park to Foley Square. Media reported that about 10,000 attended but, as Trump would say, it looked like more than that to me.
