In a live post-debate "Kelly File," Frank Luntz talked to a focus group of Republican voters.
The group expressed their dissatisfaction with the performance of Donald Trump.
Overall, Luntz noted that the majority of the group had a positive view of Trump going in, but that was not the case by the end of the two-hour debate.
Luntz said that his reaction meters showed a very negative response to Trump refusing to rule out a third-party run.
When asked which candidates surprised them, the voters pointed to Mike Huckabee and Ben Carson.
