"With zero Trump in tonight's debate, there are now 24 million viewers up for grabs and I am grabbing them," Colbert said. "If Fox News has no Trump, then I am all Trump."

When Colbert asks the business mogul how he feels about the Hawkeye State, a clip plays of Trump saying "I love Iowa, we've done very well here."

Colbert then poses that question to the "other" Trump and another clip shows him saying "How stupid are the people of Iowa?"

"We will find out on Monday," Colbert responds, referring to next week's Iowa caucuses.

He also plays a clip from a 2011 interview where Kelly asks Trump if he thought he would be a better moderator than her.

"No, I could never beat you," the billionaire responds. "That wouldn't even be close. That would be no contest. You have done a great job by the way, and I mean it."

Colbert then plays a clip from Wednesday of Trump attacking the Fox News anchor.

"I have zero respect for Megyn Kelly, I don't think she's very good at what she does and I think she's highly overrated," Trump says.
