He professes admiration for Vladimir Putin, not just a desire to pursue better relations with an adversary but approval of Putin’s despotism. He’s applauded the Chinese government’s bloody suppression of the Tiananmen Square protests.

He wants to end alliances that have kept us safe for decades because he thinks our friends are more expensive than our enemies.

He thinks more countries ought to have nuclear weapons.

He would start a global trade war that could plunge us into a depression.

He fantasizes about circumventing the First Amendment to make it easier to punish his critics.

He’s promised to murder the wives and children of terrorists, and to order American soldiers to commit other war crimes.

That’s just a partial to-do list for a President Trump, but you get the picture. He is unfit for the office, and a danger to the country and the world.

His campaign’s new hires know that, as do the Chris Christies and Newt Gingriches of the world, who make excuses for him. Working for Trump might not trouble de facto campaign manager Paul Manafort, who’s worked for tyrants on several continents. Having reached retirement age, he probably just finds it more convenient to work for one with whom he shares a home address, Trump Tower.

Maybe it doesn’t bother the conscience of any of Trump’s enablers. But it should. And it should trouble the rest of Republicans that we are identified with them.
