His hard core supporters won't care, but this may sway undecideds and third partiers. Not surprised at all.
His apology tops the old tape's content. Brings in Bill Clinton, and "I apologize if any one was offended" !!!!
After the initial shock at hearing the tape has worn off, I am thinking - how surprising is it. And this cannot be the last straw. I wonder if the debate will become like a reality show, and uncontrollable. It is already awkward when Trump and this unbelievably crazy election topic comes up in 'international' groups, like the family whatsapp that has people who are settled in countries around the world.
