According to Washington Post trackers, there have been at least four national protests during the Trump presidency to bring out over one million Americans each.
Since President Trump’s inauguration, the United States has seen four enormous protests — each with well over 1 million participants — objecting to the administration and its policies: the 2017 Women’s March, the 2018 Women’s March, the national student walkout on March 14 and the March for Our Lives on March 24.
That the two student protests were so massive, despite little time to organize, is testimony of how raw student feelings are on the issue of gun violence. NRA rhetoric may still be the order of the day among (conservative) political leaders, but up-and-coming voters are repulsed enough by it to come out in massive numbers to say so. (The Post reports roughly 4,470 individual student events on March 14 alone.) The Women's Marches, as well, are the product of widespread revulsion at conservative efforts to chip away at women's rights and conservative contempt for women in general, as demonstrated by the elevation of a nose-honking misogynistic clown into the party's—and the nation's—top position.
When you look at the issues that are bringing Americans into the parks and streets, they continue to be civil rights issues. From Black Lives Matter to March for Our Lives, demands for civil progress against state-sponsored or state-coddled violence are active and angry; demands for civil retrenchment, despite all the bleatings of Republican leaders and the feverish attempt by the New York Times to find any connecting thread among Trump voters other than gullibility and racism, are not. The tiki torch-wielding mobs of Charlottesville were small and petty; gun-rights protests intended to counter marching students have been minuscule affairs. There are no crowds marching to demand Trump's crookedness be protected or forming human chains around Mar-a-Lago to protect him from evil federal prosecutors, at least not yet. The rabid populism that has overtaken some European countries is not present here. The Trump-led version is borne primarily of aggrieved indifference, and tends to make most of its demands from the couch.
America is not going quietly into that good night. Whatever's being said on the television sets, the momentum continues to be on the side of those that would reform the country, rather than those that would sell it off for parts. So that's something.
