Biden’s economy polling is lower because Republicans won’t give him credit for anything and Dems have more complex views on American capitalism that make us hesitate to approve of any President’s economic management.
But like I said, inflation has cooled and unemployment is low, so voters may prioritize other issues when they go to the polls. If we were deep in a recession I’d feel differently, but we’re not. (Sorry Riverwalk, wherever you are)
And besides, even when the economy was more prescient back in 2022, it still wasn’t enough for MAGA candidates to win.
If gas prices fall in a close enough time frame to the election, and if interest rates finally get cut, that could make a difference for Biden, positively. Obviously they're big "ifs" though.
