Republicans continue to slide in US polls, four weeks before midterm elections

Key Points:

• Four weeks before the November 3 US midterm elections, Democrats lead Republicans by 9.6 points on the generic ballot, maintaining strong chances to control both the House and Senate according to Nate Silver’s forecast model.
• Donald Trump’s net approval rating remains low at -22.5, with particularly poor ratings on inflation (-48.5) and the economy (-32.8), which could negatively impact Republican prospects.
• Economic factors such as petrol prices and inflation, influenced by ongoing Iran war disruptions, are key variables; if petrol prices remain high, Republicans risk significant losses, but if prices fall, they may perform better and possibly retain Senate control.
• Democrats currently have a 74% chance to win the Senate and a 93% chance to win the House, with polling showing Democratic leads in key Senate battleground states that Trump won decisively in 2024.
• Economic data shows mixed signals: modest job growth, a slight rise in unemployment due to higher participation, record-high stock market levels, and a declining personal savings rate, all of which could influence voter sentiment ahead of the midterms.
