The most that can be achieved, and it’s a lot, actually, is to convey to the swing voters — the independents, suburban women and moderate Republicans who delivered the House to the Democrats in the 2018 midterms — just how much this president is ready to put himself above the law. And, therefore, four more years of his presidency, when he would no longer be “restrained” by the need for re-election, would be catastrophic for our country’s unity and for the institutions and norms that have sustained it since 1776.
