jeb bush had intense moments last night. he traded blows with donald trump and many people say today that it might be enough to revive what was a bit of an anemic candidacy. will it turn around his poll numbers? we have an opportunity to ask him. >> alisyn camerota, showing the discretion that comes with the candidate sitting immediately to your right. we have republican presidential candidate, former governor jeb bush. >> alisyn, you stalled out right there. you were about ready to take a shot and you didn't even feel it. >> it's tough with you sitting right there. let's talk about what many say is your possibly biggest night. how did you feel last night? >> i feel good. kudos to cnn for having a substantive debate. there was not a single process question. people are scared. they want to know what people believe about how to protect the homeland. we had a substantive debate about foreign policy and the importance of american leadership. there's differences of opinion. those all got expressed.
