Yet the Republican nominee has offered up a conflicting perspective on his chance of winning in recent public appearances, sometimes blowing off negative poll results as “phony” and other times telling his rally crowds that he’ll consider his presidential run a “waste of time” if he loses.
In a CNN profile out Monday, Trump’s campaign manager described her efforts to get her candidate to keep up a sunny outlook and avoid distracting tangents.
"You and I are in a fight for the next 17 days," Conway said she told Trump on the campaign plane after he diverted from a planned Saturday speech in Gettysburg, Pennsylvania to threaten lawsuits against the women who have accused him of sexual harassment.
When Trump asked why, Conway said: "Because I know you're going to win. And that comment you just made sounds like you think you're going to lose. And we're going to argue about it until you win."
According to Conway, Trump replied, “Okay honey. Then we’ll win.”
Yet as Conway herself admitted, she can only do so much to keep Trump on-message.
"People will seriously say, 'Can't you delete his Twitter account?'" Conway told CNN.
"I'm not going to take away— it's not for me to take away a grown man's Twitter account," she went on.
Trump has used his account to hype fears that the election results will be “rigged,” attack his accusers as “liars,” and start fights with everyone from a former Miss Universe to the president of Mexico.
