The Women’s March on Washington defied all expectations, drawing an estimated 500,000 protesters to the D.C. event alone, and many thousands more to sister demonstrations throughout the country. But what is next for the movement at large? Will it blossom into a political force akin to the Tea Party, which formed on the right following Barack Obama’s election eight years ago and pushed Republicans to a House majority in the 2010 midterms? Or will an overly broad focus splinter its efforts to counter the Trump administration’s agenda? Organizers of the march are aware that the world is watching.
