People need to research the election of 1980. Reagan won easily despite overwhelming media attacks throughout the campaign (including polls showing his campaign in the tank).
That was at a time when the major media was held in higher regard than it is today.
So Trump will need to speak directly to the people and attack the media liars and their phony polls.
Meanwhile Hillary is in dire physical condition (which the media is trying to cover up as best they can) and clearly does not have the stamina to match a determined Trump campaign.
The anti-Hillary ad that we may see coming will show one of her mini-seizure videos and a nuclear red button next to her shaking hand...if this campaign gets as ugly as I think it will.
That would be particularly effective with no narration.
Do not count on her condition being "dire" enough to prevent her getting elected. We can hope, but I would be planning for that not working.
