The 7th GOP debate (the one without Trump)

The seventh Republican debate, the last one before the Iowa caucuses, was lacking Donald Trump but still included plenty of sharp exchanges among the rest of the GOP frontrunners. Republican presidential candidates Sen. Rand Paul, New Jersey Gov. Chris Christie, retired neurosurgeon Ben Carson, Sen. Ted Cruz, Sen. Marco Rubio, former Florida Gov. Jeb Bush and Ohio Gov. John Kasich participated in the Fox News/Google GOP debate on January 28, 2016, at the Iowa Events Center in Des Moines, Iowa.  Donald Trump organized an alternative event at Drake University to benefit U.S. veterans.

Former Virginia Gov. Jim Gilmore, who had been excluded from many of the prior debates due to his low poll numbers, made the most of his time in the undercard debate, which included former Pennsylvania Sen. Rick Santorum, businesswoman Carly Fiorina, and former Arkansas Gov. Mike Huckabee. (Yahoo News)
