Former New Jersey Gov. Chris Christie (R) said on ABC's "This Week" Sunday that President Trump is on track to lose against former Vice President Joe Biden in November "if he doesn't change course both in terms of the substance of what he's discussing and the way that he approaches the American people."

Driving the news: Both state and national polls in recent weeks have shown Biden gaining a commanding lead against Trump. At a Fox News town hall last week, Trump told Sean Hannity that Biden "is going to be president because some people don’t love me, maybe" — an apparent acknowledgment of the dire state of his re-election campaign.

  • Trump is also facing criticism for failing to outline his priorities for a second term in response to a softball question from Hannity.
  • The president instead offered a rambling response in which he attacked his former national security adviser John Bolton.

What he's saying: "The trend is obvious," Christie said. "The trend is moving towards Joe Biden when Joe Biden hasn't said a word. Joe Biden's hiding in the basement and not saying anything. No discredit to the vice president — if you're winning without doing anything, why do anything."

  • "The president has to change course here both in terms of the substance and answering that question much better than he did with Sean Hannity in terms of what he wants to do in his second term."

The bottom line, per Christie: "He is losing, and if he doesn't change course both in terms of the substance of what he's discussing and the way that he approaches the American people, then he will lose."

Democratic presidential nominee Joe Biden told reporters in Delaware Wednesday he believes he would have the legal authority as president to issue a nationwide mandate to wear face masks to curb the spread of the coronavirus if needed.

Details: "Our legal team thinks I can do that, based upon the degree to which there's a crisis in those states, and how bad things are for the country," Biden said.

When he talks about Russia, Joe Biden has sounded like Ronald Reagan all summer, setting up a potential Day 1 confrontation with Russian President Vladimir Putin if Biden were to win.

Why it matters: Biden has promised a forceful response against Russia for both election interference and alleged bounty payments to target American troops in Afghanistan. But being tougher than President Trump could be the easy part. The risk is overdoing it and making diplomacy impossible.

The Cook Political Report on Thursday changed its forecast of Arizona in the presidential race from "toss up" to "lean Democrat," citing new polling data that shows the Sun Belt state slipping away from President Trump.

Why it matters: The rating in a crucial swing state doesn't bode well for President Trump's re-election chances. He won the state by more than 3 points in 2016.
