Public and private polling shows President Trump "not only trailing badly in swing states like Michigan and Wisconsin, but running closely with [Joe] Biden in traditionally conservative bastions like Kansas and Montana," the New York Times reports.

Why it matters: Trump won each of those states in 2016 by 20 points. If he's in dogfights there, his map is on fire.

  • Tim Murtaugh, Trump campaign communications director, replied: "That’s nonsense. In our data, President Trump is strong against Joe Biden in all the states we track and which will decide the election."
  • "Our plan has always been, and remains, to retain the states the President won in 2016 and add some more to his column. We will be playing on Biden’s field in states like New Hampshire, Minnesota, New Mexico, and Nevada."

Murtaugh said the campaign’s polling shows openings based on the defunding police issue, which is “why you see us on offense in states we didn’t win in 2016."

Joe Biden leads President Trump 48% to 42% in Wisconsin and 49% to 43% in Pennsylvania, according to the latest CBS/YouGov Battleground Tracker poll.

Why it matters: Trump's surprise wins in the two states, where many voters broke his way after deciding the week before the election, helped propel him to an Electoral College victory over Hillary Clinton. Trump won Wisconsin with 47% of the vote and Pennsylvania with 48% in 2016, according to the New York Times.

Two weekends ago, President Trump met with a group of his closest aides in the conference room of his Bedminster golf club to discuss a subject that has been weighing heavily on his mind: the three scheduled debates with Joe Biden.

Behind the scenes: In the room with Trump were his son-in-law Jared Kushner, campaign manager Bill Stepien, senior adviser Jason Miller, and former New Jersey Gov. Chris Christie, who role-played Hillary Clinton in Trump's 2016 debate prep sessions.

Fifty-two percent oppose fracking in a CBS News poll of registered voters in Pennsylvania, while 48% favor the oil-and-gas extraction method, a finding within the poll's margin of error.

The big picture: Pennsylvania is a key swing state where natural gas development is a major industry, and President Trump's campaign has sought to turn Joe Biden's energy plans into a political liability.
