Donald Trump saw it coming. Back in 2019, the moderate Joe Biden looked like a candidate uniquely suited to threaten his re-election as president. In a July 25 phone call, Trump asked Ukraine’s president Volodymyr Zelensky to have his government work with his lawyer, Rudy Giuliani, and with then-US Attorney General William Barr to launch an investigation of Biden and his son Hunter.

That call, which Trump defended as “perfect,” and the administration’s pausing of security aid to Ukraine, would become the focus of his first impeachment, which ended with Trump’s acquittal in the Senate.

The former president never could solve the riddle of how to defeat Biden, who he accused of being a puppet for the “radical left.”

In reality, Trump lost to him because the coronavirus pandemic changed everything — but only some people got the message. One of them was Biden.

In a speech to a joint session of Congress Wednesday, with a soft-spoken, almost whispered urgency, President Biden made his case for a breathtaking overhaul of America’s social contract.
