Aug. 1, to be exact — the day renowned Hillary Clinton-critic Maureen Dowd published a column that marked a turning point in the presidential speculation.

According to multiple sources, it was Biden himself who talked to her, painting a tragic portrait of a dying son, Beau’s face partially paralyzed, sitting his father down and trying to make him promise to run for president because “the White House should not revert to the Clintons and that the country would be better off with Biden values.”

It was no coincidence that the preliminary pieces around a prospective campaign started moving right after that column. People read Dowd and started reaching out, those around the vice president would say by way of defensive explanation. He was just answering the phone and listening.

But in truth, Biden had effectively placed an ad in The New York Times, asking them to call.
