During a live post-debate "Kelly File," Frank Luntz talked to a focus group of Republican voters about their reaction to the third GOP debate.

The participants had an overwhelmingly positive response to Ted Cruz's criticism of the CNBC debate moderators and their "biased" line of questioning.

"The questions that have been asked so far in this debate illustrate why the American people don't trust the media," Cruz said to applause. "How about talking about the substantive issues?"

On a scale of 0 to 100, both conservative and moderate participants hit as high as a 98 favorable rating to Cruz's statement.

Luntz revealed that in more than 15 years of focus groups, no line had ever been received so favorably.

Watch more above to hear exactly what the focus group thought of Cruz, the debate and the moderators.
