QUOTE : Martin Luther King Jr. was the greatest movement leader in American history. But, as Hillary Clinton once correctly pointed out, his efforts would have been futile without those of the machine politician Lyndon Johnson, a seasoned congressional deal maker willing to sign any pact with the devil to get the Civil Rights Act and Voting Rights Act passed. And the work doesn’t stop once legislation is passed. One must keep winning elections to defend the gains that social movements have contributed to. If the steady advance of a radicalized Republican Party, over many years and in every branch and at every level of government, should teach liberals anything, it is the absolute priority of winning elections today. Given the Republicans’ rage for destruction, it is the only way to guarantee that newly won protections for African-Americans, other minorities, women, and gay Americans remain in place. Workshops and university seminars will not do it. Online mobilizing and flash mobs will not do it. Protesting, acting up, and acting out will not do it. The age of movement politics is over, at least for now. We need no more marchers. We need more mayors. And governors, and state legislators, and members of Congress . .
