It is not necessary to dictate reactions. I watched the debate in a room where the volume was very low and visual cues became much more prominent. I honestly felt that the Vice president looked boorish and incredibly disrespectful. I have come to expect that there will be occasional interruptions in a debate; however the Vice President's interruptions were so ubiquitous that it became rapidly apparent that it was a tactic to bully his opponent. The media pundits merely echoed my own impressions. I find value in their insights because they historical experience covering debates and can give context to the behavior of the participants. Ryan gave far more specifics than Biden. I believe you have mistaken blowhard platitudes for knowledge.
