President Donald Trump is set to deliver his prime-time State of the Union address on Tuesday night as polls indicate voters are souring on his economy, after he made promises to lower prices for working-class voters.

Trump will speak at a critical moment. The midterm elections, looming less than nine months away, threaten to rip away the near-complete control of Washington he has enjoyed in his second term. And public polling indicates Trump is sinking on what were once his key issues: the economy and immigration.

The economy is expected to feature heavily in Trump’s address, especially after the Supreme Court last week overturned his authority to issue a wide swath of his tariffs — a key plank of his economic platform.

“You’re going to hear a lot about the importance of bringing jobs back to our country,” Vice President JD Vance said in a Fox News interview on Saturday. “I think he’s going to talk about regulatory change, the importance of lowering energy prices for American citizens.”

High prices for everyday goods are one of the biggest problems facing Trump in his second term. Democrats are hounding the president and other Republicans on affordability, an issue that resonates with voters.
