But as the group moved together for the perfunctory photo, Rachel Binah, a former Richardson delegate who now supports Hillary Clinton, told Bill how “sorry” she was to have heard former Clinton campaign manager James Carville call Richardson a “Judas” for backing Obama.

It was as if someone pulled the pin from a grenade.

“Five times to my face (Richardson) said that he would never do that,” a red-faced, finger-pointing Clinton erupted.

The former president then went on a tirade that ran from the media’s unfair treatment of Hillary to questions about the fairness of the votes in state caucuses that voted for Obama. It ended with him asking delegates to imagine what the reaction would be if Obama was trailing by just 1 percent and people were telling him to drop out.

“It was very, very intense,” said one attendee. “Not at all like the Bill of earlier campaigns.”
