I don’t want Trump to succeed. I want him to fail spectacularly.

But make no mistake — success for Trump would be a disaster for America. If his campaign promises are to be taken at face value, his success would mean that tens of millions of Americans may lose health care insurance. It would mean a step back on fighting climate change that could have a catastrophic, even apocalyptic effect on the planet. It would mean a shredded social safety net and little federal attention to voting restrictions and structural racism in America’s criminal justice system. It would mean global instability and a weakening of American’s leadership role in the world. It would mean acquiescence to an assertive Russia and a weakening of the international institutions that help to maintain global order. It would mean disastrous trade wars and a domestic agenda that would do more to harm the people who voted for Trump than help them. It would mean mass deportation — and a humanitarian catastrophe — for millions of undocumented immigrants.
