Here is some new polling. According to this, Biden is seen as better on the economy, which is a switch:
The August 2020 Battleground Poll gave strong evidence that three months out from the 2020 election, President Trump faces eroding support on the economy, and major challenges with Independent, suburban, and middle class voters. Americans trust Vice President Joe Biden more than President Trump on key issues, including the economy, where 49% of voters say they have more confidence in Biden, and 47% have more confidence in Trump. Democrats have a much more narrow lead on the Congressional ballot, which finds Republicans at a disadvantage of just six points (44%-50%) despite voters trending toward Biden on key issues.
The approval rating hasn’t budged much:
As usual, I’m shocked at how high Trump’s numbers are but then I remember that 39% of the public voted for Herbert Hoover in 1932. They’re always there, no matter how bad the candidate might be.
