A Stephen Colbert-moderated debate between Donald Trump and Donald Trump would be a ratings bonanza.

The ratings for both Trumpapalooza: The Rally and Trumpapalooza: The Debate were a bit disappointing—Trump obviously cut into Fox News’s reach, but he didn’t create bona fide competition for the Republican Hunger Games. 

Stephen Colbert has an answer for Trump’s woes with Fox and the RNC, however: Donald Trump should debate himself and, once and for all, settle the question of how he really feels about the people of Iowa, Megyn Kelly, and Ted Cruz.
