First off, I am perfectly able to understand what she means. Perhaps it was not the most eloquent way to put it, but I understood every word and the sentence made sense.

Secondly, I can match your examples 1000 to 1 of times she was very well-spoken. One example, one in which she does not stutter or mispronounce any words, means nothing. I know you know it means nothing. She has spoken so, so, so many times throughout her career.
