John McCain’s presidential campaign was going downhill, and he wasn’t seriously playing in New Jersey politics. Now the McCain National Finance Co-Chairman (titles aside, he’s McCain’s #1 money guy). If McCain is president, Eisenberg can pretty much have anything he wants: Secretary of the Treasury? Ambassador to the Court of St. James? It really could be his call.
