Broad and principled opposition to Donald Trump's presidency has drawn millions of previously disengaged citizens to the public square and to the ballot box. This inspired and growing activism for social and political change hasn't been seen since the days of Franklin Roosevelt's New Deal policies and the Progressive and Civil Rights movements. But if progressives and moderates are unable - and unwilling - to overcome their differences, they could not only enable Trump to prevail again but also squander an occasion for launching a new era of reform. In Code Red, award-winning journalist E. J. Dionne, Jr., calls for a shared commitment to decency and a politics focused on freedom, fairness, and the future, encouraging progressives and moderates to sustain the unity that brought about Democrat victories in the 2018 elections. He offers a unifying model centered on solving problems, restoring dignity to those left behind, and tackling issues like gun violence, low wages, and health care. Dionne offers a compelling strategy for progressives and moderates to think more clearly and address the responsibilities that history now imposes on them. Because at this point in our national story, change can't wait.
