The Democratic establishment is giddy right now about all the new enthusiasm, but veteran organizers warn that it will be harder than it looks to channel it toward sustained engagement in the political arena. "Saturday's marches, which featured speeches from many leading Democrats, were not explicitly Democratic events," The Washington Post's Dave Weigel and Jenna Portnoy note. "Melissa Byrne, a candidate for DNC vice chairman, said that the crowds . . . will encourage even more people to become activists. But having organized for Barack Obama's 2008 campaign and for the Occupy D.C. movement, she saw how the new activists would be tested even if the rallies grew in size. 'People are going to get frustrated, because you want your wins to come quickly,' she said. 'For people who are new to this, it takes a while to get that.'"
