Tip O'Neill once wrote of the first time Gerald Ford entered to address Congress after he'd ascended to the highest office in the land. The gent in charge of yelling out such things yelled out, "Mister Speaker, the President of the United States!" And then everyone — Democrats and Republicans alike — looked over, reassured themselves that it was indeed Gerald Ford walking in, and let out a cheer that it was not Richard Nixon.
I think I just saw a similar moment.
