Goldberg Interviews J Street Chief

It's a useful and illuminating bit.

UPDATE: I didn't think of this at the time, and I bet it's coincidence, but the triangulation move Mr. Ben-Ami takes vis-a-vis the Jewish anti-Zionist far-left strikes me as a telling repudiation of those same groups (intentional or unintentional) attempts to sabotage J Street's efforts to establish itself as a credible voice for the Jewish mainstream.
