No, it isn't just you. It was definitely in the range of "polite applause" at best. The longest applause lasted maybe 3 seconds.
I noticed he constantly used the royal "WE" and "OUR". His whole speech was a lie. He's never done one good thing for the veterans and did NOTHING for the MIA/POWs. He and McCain tried to sully the names of the wives of these men. "He, as president, is going to make sure our fighting forces have the equipment and armament they need". Yeah, sure. He's already proved how he made sure our guys and gals in Iraq got the money for their equipment and armament.
OOOO this fellow is truly the "vietnam candidate".
