Trump will destroy Hillary on National TV.
The debate will be the final nail in Hillary's coffin.
By 1 Oct., Trump will have an insurmountable lead in the polls. The MSM will declare the election over.
He may not have to. She could very well self-destruct and have another health breakdown. That is a situation Trump needs to be ready to exploit by just letting it happen. "Never interrupt your opponent when he's making a mistake." - Napoleon Bonaparte.
If Hillary has a health episode in the debate, its a run out the clock situation because the game is over.
Who is moderating the first debate? I expect a very well coordinated attack on Trump between Hillary and whoever moderates.
