Obama calls Trump 'wannabe king' at Harris event

In his fourth visit to the swing state of Arizona, vice presidential nominee Sen. JD Vance had one simple message to voters: get out and vote for Trump.

"Here's the scenario that I want you to consider, and I don't mean to give you nightmare fuel here, but I'm going to do it," Vance said. "We wake up on November the 6th and Kamala Harris is barely elected President of the United States by a 700-vote margin in the state of Arizona. Think about that and ask yourself what you can do from now until then to make sure it doesn't happen."

Asked by local reporters what's the strategy to get across the finish line with those who are still undecided, Vance asked them to look at the former president's record, arguing that America was in a better position with him as commander-in-chief.

Asked if he's confident in the Arizona election system and if he's going to accept the results of the 2024 election, Vance said he thinks "that we're in a better place than we were in 2020."

Harris acknowledged Tuesday that “of course” it is possible that Trump could declare victory before all the votes are counted next month.

"This is a person, Donald Trump, who tried to undo a free and fair election, who still denies the will of the people, who incited a violent mob to attack the United States Capitol and 140 law enforcement officers were attacked, some who were killed," Harris told NBC's Hallie Jackson in a clip of their interview that was released Tuesday afternoon.

Harris said that she and her team "will deal with election night and the days after as they come, and we have the resources and the expertise and the focus" on that scenario.

The Georgia Supreme Court on Tuesday denied an effort from the Republican National Committee to reinstate a series of election rules, including requiring ballots be counted by hand, after they previously were blocked by a lower judge.

The state's high court ruling was unanimous, according to the order.

The lower court judge previously ruled that seven election rules passed by the state's Republican-led Election Board were "unlawful and void." The RNC then appealed, with RNC chairman Michael Whaley in statement saying the judge "exemplified the very worst of judicial activism."

The order from the Georgia Supreme Court on Tuesday said the appeal "will proceed in the ordinary court" once it is docketed.

Over 21 million Americans have voted early as of Tuesday afternoon, according to data from Election Lab at the University of Florida.

Roughly 7.8 million votes have come in through early in-person methods while the remaining votes -- over 13 million -- have been cast through mail ballots, the data showed.

There is a large showing of early votes in the swing state of Georgia which has seen record early vote turnout since early in-person voting began last week.

As of Tuesday afternoon, more than 1.84 million Georgians, roughly one in four registered voters, have cast their ballot, with over 1.74 million votes cast at early voting polling places across the state according to Georgia's Secretary of State office.
