The mere prospect of a Donald Trump presidency is already hurting America’s global image, according to a high-level group of diplomats and elected officials across Europe and the U.S..

“A madman,” “clown,” and “freak politics,” is how opinion-leaders in POLITICO’s fourth Transatlantic Caucus summed up the real estate tycoon and his controversy-filled campaign for the Republican nomination.

The view was overwhelming: 83 percent of Caucus participants said Trump’s candidacy damages America’s standing in the world.

“Donald Trump’s rhetoric and simple-minded approach is dangerous to American standing in the world,” said one Caucus member. “He offers nothing good for the U.S. or the world at large.”
