Another reason why I don’t expect this speech to develop into a ‘draft Rudy’ campaign is his voice. Either Rudy was having a bad sinus day, (something I’m very familiar with) or he had some other minor physical problem.
Rudy’s delivery sounds strained and pushed out of the throat. Sometimes, the velocity of emotion overwhelms the throat, and the speaker lets it out as the feelings wash over him.
So he may have been riding the tidal wave of emotion that comes from finally saying- blurting out loud what you have thought about for years. Maybe it’s just the effects of age and nothing more.
