A man in a black hat opens his mouth.
The governor prepared to deliver the speech that would deliver the votes.
The man doesn't have to be a governor, not all governors are men and opening his mouth doesn't mean he is going to deliver a speech.
Just because a man in a black hat opens his mouth it does not mean the man is a governor or that he is prepared to deliver a speech.
All men in black are not governor and opening a mouth does not necessarily mean delivering a speech.
