PROVING GROUND: What do candidates need to do to stand out from the crowd? Longtime Republican strategists David Kochel and Dave Carney give their thoughts and predictions:

  • Ron DeSantis "needs to broaden the appeal… [and] draw a distinction between himself and Trump."
  • Nikki Haley may take verbal attacks from others on the stage. She got a spike after the first debate, but "what do you do with that momentum? Is it a flash in the pan or can you repeat that performance and have an upward trajectory in the race?" Kochel said.
  • There’s "going to be a lot of pressure on someone like Tim Scott, who disappeared a bit in the first debate, to step up and do better."
  • Mike Pence: "if I were him, I would be touting myself as the Reagan conservative in the traditional sense and take off after populism," Kochel said.
  • Vivek Ramaswamy was a punching bag in the first debate, but now he has to prove that he's presidential — and that no one else attempts to take the Trump heir-apparent track, Carney said.
  • Chris Christie wanted to debate Trump — but Trump won't be there. "My guess is he’ll probably throw more haymakers at Ramaswamy because he’s [the] most Trump-like person on the stage," Kochel said.
  • Doug Burgum, the least well-known candidate on the stage and the last to qualify for the second debate, has to find a way to stand out, said Carney.

SIDELINED: Asa Hutchinson is the only candidate from the first debate who failed to qualify for the second contest. But he's pushing forward with his campaign. 

"I understand that the [Republican National Committee] and the media are trying to reduce the number of candidates, but I measure success based on the response I receive in early primary states like Iowa and New Hampshire," Hutchinson wrote this week in a statement on X, formerly Twitter.
