Joe Biden on Tuesday traveled to Gettysburg, Pennsylvania, home to the Civil War battlefield where Abraham Lincoln once called for national unity, to ask Americans to come together to defeat racial injustice and the coronavirus.

Why it matters: Pennsylvania, a swing state that was crucial to President Trump's 2016 win, could deliver the election to Biden next month. A new Monmouth University poll out Tuesday shows Biden expanding his lead over Trump in the state.

The big picture: Biden is contrasting his approach with Trump's on two of the key challenges gripping the nation.

  • The president has positioned the racial justice debate as a choice between police and rioters. He continues to minimize the dangers and precautions around COVID-19 even after his hospitalization and treatment with experimental therapeutics.
  • On Tuesday, Trump also instructed Republicans to abandon stimulus talks with Democrats until after the election.

What they're saying: "We must come together as a nation," Biden said. "I believe in law and order. I don’t believe we have to choose between law and order and racial justice."

  • After Biden spoke, Trump tweeted: "How does Biden lead in Pennsylvania Polls when he is against Fracking (JOBS!), 2nd Amendment and Religion? Fake Polls. I will win Pennsylvania!"

Pennsylvania Supreme Court rules mail-in ballots can't be rejected for mismatched signatures

The Pennsylvania Supreme Court ruled unanimously on Friday that election officials cannot reject a mailed-in ballot because a voter’s signature may not resemble the one on their registration form.

Why it matters: The decision comes as a win for voting rights advocates and Democrats who say the signature disqualification rule can disenfranchise voters. In 2016, it was the top reason that ballots were rejected, with 28% of disqualified ballots flagged for non-matching signatures, according to the Election Assistance Commission.

Hunter Biden saga dominates online debate

Data: NewsWhip; Table: Axios Visuals

The mainstream media turned away. But online, President Trump's charges about Hunter Biden were by far the dominant storyline about the final presidential debate, according to exclusive NewsWhip data provided to Axios.

  • Coverage of business dealings by Joe Biden's son — and pre-debate allegations by one of his former business associates, Tony Bobulinski — garnered more than twice as much online activity (likes, comments, shares) as the runner-up.

President Trump cast his ballot in Florida on Saturday ahead of a jam-packed weekend of campaigning just 10 days ahead of the general election.

The big picture: Trump registered as a Florida voter in 2018, citing his Mar-a-Lago residence. His in-person vote comes amid a massive uptick in mail-in voting due to the coronavirus pandemic, but Trump argues mail-in voting is typically unsafe and ripe for fraud.
