Forget about Donald Trump’s uncountable failings as a human being, what he represents more than anything else is the past — his support derives almost wholly from those who desperately cling to the past, unwilling to accept and embrace the world in which we do indeed now all live.

America would do well to see in Ireland a representation of the future this country will enjoy once it musters courage to advance all the way to the present.

Scott Simon: Ireland’s center-right Fine Gael Party has elected Leo Varadkar as its leader and therefore next prime minister. He’ll be Ireland’s youngest leader at 38. He’s the son of an Irish nurse and a doctor from Mumbai. He told the party conference, when my father traveled 5,000 miles to build a new home in Ireland, I doubt he ever dreamed his son would grow up to be its leader.

Mr. Varadkar is also gay. He was a doctor like his father before entering politics and was elected to Parliament, then minister of health. Leo Varadkar is considered a free market economic conservative who says, I want to dedicate ourselves to building a republic of opportunity. The next prime minister of Ireland is a 38-year-old Indian gay conservative. Only in America – oh, wait.
