Yes, always that fear of being insulted in these forums but hey'insults are the last refuge of the intellectual coward; the tools of the ignorant and uninformed. 
Nonetheless, this was all about strategy.  The democrats' case was laid out by the ranking member and everyone else simply aimed to get 'data' into the record.  They were asking questions they KNEW the CIA and the FBI would not be able to answer.  In fact they often prefaced their 'questions' with, I know you probably wont be able to answer this but...  The goal of the repubs was to focus on leaks because they couldnt risk making themselves or their party look bad (or any worse).  The goal of the hearing was to answer two questions, is 45 and his merry band being investigated, and did he tell a lie about BO.  Both were, everything else was a dog and pony show.
