"Republicans Grapple with Urgency to Challenge Trump in Second Presidential Debate"

Republicans are entering their second presidential debate with a growing urgency to stop Donald Trump, who continues to dominate the field despite facing vulnerabilities such as criminal indictments. Trump will not be sharing the stage with his top rivals, opting instead to deliver a prime-time speech in Michigan. Nikki Haley and Ron DeSantis are hoping for breakout moments, while other candidates like Mike Pence and Vivek Ramaswamy are seeking to make up ground. The debate comes at a critical moment in the GOP campaign, with less than four months before the Iowa caucuses.
