Former Vice President Joe Biden is leading President Trump in all six 2020 battleground states tracked by a CNBC/Change Research poll out Wednesday.

Why it matters: It's the first time Biden has led across all six states in this poll, reflecting his growing momentum both nationwide and in critical swing states needed to win the election.

  • Biden's lead has widened in recent polls amid the coronavirus pandemic and widespread protests against police brutality and systemic racism.
  • The battleground advantage comes a week after a Gallup poll showed Trump's net approval rating dropped 19 points in a month.

By the numbers:

  • Arizona: Biden 45%, Trump 44%
  • Florida: Biden 50%, Trump 43%
  • Michigan: Biden 47%, Trump 45%
  • North Carolina: Biden 47%, Trump 45%
  • Pennsylvania: Biden 49%, Trump 46%
  • Wisconsin: Biden 48%, Trump 44%

Worth noting: The poll also found that 45% of likely voters in the six states approved of Trump's handling of the coronavirus crisis, while 55% disapproved.

  • 44% approve of Trump's handling of police violence and discrimination, while 56% disapprove. 
  • 52% of respondents said Trump's response to the police killing of George Floyd and the ensuing protests was harmful, compared to 23% who said it was helpful. 

Methodology: The CNBC/Change Research poll surveyed 2,408 likely voters across the six states June 12-14. It has a margin of error of ±2 percentage points. Go deeper.

The Biden blowout scenario

Joe Biden or President Trump could win the election narrowly — but only one in a popular and electoral vote blowout. 

Why it matters: A Biden blowout would mean a Democratic Senate, a bigger Democratic House and a huge political and policy shift nationwide.

In an urgent appeal on Thursday, Sen. Bernie Sanders (I-Vt.) said President Trump presented "unique threats to our democracy" and detailed a plan to ensure the election results will be honored and that voters can cast their ballots safely.

Driving the news: When asked yesterday whether he would commit to a peaceful transfer of power if he loses, Trump would not, and said: "We're going to have to see what happens."

Democratic lawyers are preparing to challenge any effort by President Trump to swap electors chosen by voters with electors selected by Republican-controlled legislatures. One state of particular concern: Pennsylvania, where the GOP controls the state house.

Why it matters: Trump's refusal to commit to a peaceful transfer of power, together with a widely circulated article in The Atlantic about how bad the worst-case scenarios could get, is drawing new attention to the brutal fights that could jeopardize a final outcome.
