标题:Joe Biden’s tragic curtain call

Hubris kept him too long in the presidential race and he will be remembered chiefly for easing Trump’s return

正文： If the essence of Greek tragedy is that the hero is undone by his flaws, Joe Biden gets star billing. He defeated Donald Trump, stood up to Russia, enacted more reforms than Bill Clinton and Barack Obama and bequeaths a robust economy. That made Biden a hero to America’s left and beyond. Yet most of his achievements will now be erased. His legacy is Trump’s return. After Biden, the deluge. He largely has himself to blame.
