  • Donald Trump’s campaign says he’ll skip GOP debate, citing perceived unfair treatment from Fox
  • Sheriff Joe Arpaio of Arizona’s Maricopa County says he’s backing Trump for president
  • Hillary Clinton promises an extension of the Obama years while Bernie Sanders calls for a political revolution, setting up a choice for Democratic voters, the Times’ Cathleen Decker writes
  • Our takeaways: The unusual format did little to break new ground or stop the candidates’ attacks
