"By the narrowest of possible margins, the keys still point to a Trump victory. However, there are two major qualifications. And I’m not a hedger, and I’ve never qualified before in 30 years of predictions.

"Qualification number one: It takes six keys to count the party in power out, and they have exactly six keys. And one key could still flip, as I recognized last time — the third party key, that requires Gary Johnson to get at least five percent of the popular vote. He could slip below that, which would shift the prediction.

"The second qualification is Donald Trump. We have never seen someone who is broadly regarded as a history-shattering, precedent-making, dangerous candidate who could change the patterns of history that have prevailed since the election of Abraham Lincoln in 1860.

"I do think this election has the potential to shatter the normal boundaries of American politics and reset everything, including, perhaps, reset the keys to the White House."
