 A new Reuters-Ipsos poll found that voters see Trump as the better candidate for the economy, but prefer President Biden for the preservation of democracy. Stubborn inflation has been a lingering problem for the president, which has kept his approval rating in the 30s. Trump also holds a 13-point advantage on the topic of immigration. However, Mr. Biden has more voter support when it comes to responding to political extremism and threats to democracy. Greg Clugston, Atlanta.
