The Republican candidates for president will appear on Wednesday at the University of Colorado Boulder for their third debate of the primary season. This time around, the host network is CNBC, which promises to "focus on the key issues that matter to all voters -- job growth, taxes, technology, retirement and the health of our national economy."
In the video above, The Huffington Post's Jason Linkins and Zach Carter explore five things you'll want to watch out for, including a brighter spotlight on Marco Rubio and Ben Carson.

CNBC's debate night kicks off at 6 p.m. EDT, with an undercard debate featuring Lindsey Graham, Bobby Jindal, George Pataki and Rick Santorum. The debate featuring the candidates who could actually win the nomination begins two hours later. Your moderators for the evening are CNBC's Carl Quintanilla, Becky Quick and John Harwood.
