Megadonors Are Plotting to Change Biden’s Mind With Money. Will It Work?

They’re calling politicians. They’re dangling money to members of Congress. But major Democratic donors who want President Biden to step aside are also learning the limits of their powers.

For ultrarich Democrats, this is the golden age of political scheming.

The last three weeks since President Biden wilted during the first presidential debate have uncorked a nervous energy that has stirred almost every major Democratic donor and their advisers, turning billionaires ensconced on summer vacations into crafty political animals.

They’re calling every major politician they know, encouraging them to call for Mr. Biden’s removal. They’re dangling money to members of Congress who say the right things, and withholding money from those who do not. And even the most reclusive donors are talking to reporters, sometimes on the record, about the turmoil within the party establishment.

These are chaotic times. So many ideas are bouncing around the donor class that some card-carrying members say privately that they are having trouble keeping track of all the plots. Some of the wealthiest people in the world have been locked in a perpetual, almost academic examination of how much leverage they truly have to change Mr. Biden’s mind.

Would it be best to funnel money toward a super PAC, which has raised $2 million so far, that plans to back vulnerable Democratic members of Congress who are calling for Mr. Biden’s removal? Or maybe the savvier move would be to raise money loudly for Vice President Kamala Harris, his heir apparent, as an affirmative sign that the president need not worry about passing the reins? What about setting aside some money in an escrow account that would be spent only on a Democratic presidential campaign led by someone other than Mr. Biden?
