Sarah Palin, Sen. Ted Cruz and former Sen. Jim DeMint are headlining a gathering of some 2,500 at the Western Conservative Summit in Denver.
The summit at the Hyatt Regency and Colorado Convention Center culminates Sunday with a straw poll to gauge attendees' early choices for a 2016 presidential nominee.
Also speaking at the summit are Louisiana Gov. Bobby Jindal and Utah Sen. Mike Lee.
The summit is organized by Colorado Christian University's Centennial Institute, which planned to livestream sessions on its website.
