Governor Tom Vilsack had a turn at the microphone before New York Senator Hillary Clinton and the candidates who appeared at this weekend’s Iowa Democratic Party fundraiser, but Vilsack took a verbal misstep. Vilsack gave a speech his communications director says was unscripted and “came from the heart.” As a means of emphasizing a point, Vilsack urged the crowd to join him in saying the Pledge of Allegiance. He left out the word “indivisible” however. After the event, I told him about his mistake. Vilsack insisted he had said the word, and he repeated that part of the Pledge. Walking away from me, on the hand-shaking rope-line, Vilsack made one final comment about leaving out the word indivisible. “I never did very well in math,” Vilsack said.
