We've never before seen a candidate who's spent his life enriching himself at the expense of others. He's the first candidate in our history to be a serial fabricator, making up things as he goes along. Even when he tells the truth, such as, "Barack Obama really was born in the U.S.," he adds two lines, that Hillary Clinton started the birther movement, and that he finished it, even though when Barack Obama put out his birth certificate, he didn't believe it. We've never had a candidate before who not just once, but twice in a thinly disguised way, has incited violence against an opponent. We've never had a candidate before who's invited a hostile foreign power to meddle in American elections. We've never had a candidate before who's threatened to start a war by blowing ships out of the water in the Persian Gulf if they come too close to us. We've never had a candidate before who has embraced as a role model a murderous, hostile foreign dictator. Given all of these exceptions that Donald Trump represents, he may well shatter patterns of history that have held for more than 150 years, lose this election even if the historical circumstances favor it.
