from a Senate staffer:
the caucus and leadership meetings were not love fests. Specter was forced to address the issues and his leadership of the committee, and to defend himself. Hatch in fact did exit the meeting and put his arm around Specter and endorsed him.
Conservatives are livid about Hatch’s actions, but now feel there is little that can be done. The old guard is backing him, and some more endorsements are expected tonight and tomorrow. The way it was put to me is that barring a last minute surprise, Specter has the job.
