JON KARL: Good morning. Welcome to This Week. For most of us, Election Day is already here. Virtually all of us live in places where you don't have to wait until November 5th to cast your ballot. More than 40 million Americans have already voted. This morning, we're going to talk about where the race stands, who's up in the polls, who's down, the tactics the candidates are using to convince undecided voters and to get their supporters to turn out. But this isn't a sporting event. This is about much more than tactics or polls. If there's one thing both sides agree on, it's that America is making a choice that will say a great deal about what kind of a nation we are. And what kind of a nation we may become. Four years ago, Donald Trump became the first president in American history to refuse to accept the results of a presidential election, and to do everything in his power to try to overturn the will of the people. It was an effort that continued even after he left The White House. This time, Trump once again seems to be making it clear he won't accept the results if he loses, but he might not have to. Donald Trump has a very good chance of winning this election. He might even be at this moment, the front-runner. This even after his former Chief of Staff issued a stark warning this week that Trump wants to rule as a dictator, that he meets the textbook definition of a fascist. Once again, this is not a normal campaign.
