When President Joe Biden needs advice, there are two people he can turn to who know what it’s like to sit in his chair. Sometimes he will invite Barack Obama over to the White House for a meal or he will get on the phone with Bill Clinton.

The three men share decades of history at the pinnacle of American and Democratic leadership, making them an unusual trio in presidential history. Although there has sometimes been friction as their ambitions and agendas have diverged, they have spent years building toward a similar vision for the country.

On Thursday, their partnership will be on display in what has been described as a one-of-a-kind fundraising extravaganza in New York City to help Biden build on his already significant cash advantage in this year’s presidential election. It’s a dramatic show of force intended to rally the Democratic Party faithful to secure a second term for Biden despite his stubbornly low poll numbers and doubts due to his age (81).
