The race for 2016 gets more interesting with every candidate who drops out and every debate that takes place, and Wednesday is your next chance to tune in. The third Republican presidential debate, held at the Coors Events Center at the University of Colorado in Boulder, is set for 8 p.m. EDT on CNBC. Ten candidates will participate in the main event, and four others will attend a "happy hour" debate at 6 p.m. The start time, TV channel and radio details are posted below.

CNBC said it developed its lineup based on "methodically sound and recognized national polls," which put real estate mogul Donald Trump in first place with 25.22 percent of likely GOP primary voters. Neurosurgeon Ben Carson trailed him by about 5 percentage points and Florida Sen. Marco Rubio came in third with 9.67 percent support. The other participants, in order, were: former Florida Gov. Jeb Bush, former Hewlett-Packard CEO Carly Fiorina, Texas Sen. Ted Cruz, former Arkansas Gov. Mike Huckabee, New Jersey Gov. Chris Christie, Ohio Gov. John Kasich and Kentucky Sen. Rand Paul.

Former Pennsylvania Sen. Rick Santorum, Louisiana Gov. Bobby Jindal, former New York Gov. George Pataki and South Carolina Sen. Lindsey Graham will be in the 6 p.m. showdown for lower-tier candidates.

In fact, both lineups for Wednesday were nearly the same as those for the second debate held last month by CNN. Politico noted that only Wisconsin Gov. Scott Walker, who stopped campaigning Sept. 21, will not attend.

All the candidates will explain their positions on "the key issues that matter to all voters -- job growth, taxes, technology, retirement and the health of our national economy," CNBC reported. Both showdowns will be moderated by Carl Quintanilla, Becky Quick and John Harwood.
