away. what made you choose cruz, not trump? >> well, first of all, ted cruz is a comprehensive conservative, a principled leader. i think everybody would say he has a titanium spine, delivers a very clear message and the more people listen to him, the more people are drawn to him. that's why you're seeing conservatives unite around ted cruz and you'll continue to see that in iowa and i believe across the country. so we look forward to this race and this is not against trump this is for ted cruz. >> but there has to be something about donald trump you didn't like, bob. what was it? >> donald trump is a great friend of mine but it's what i really like about ted cruz. i believe ted cruz is the leader that we need at this -- these uncertain times, especially with paris, san bernardino and others. national security, border security, they want somebody to deliver a clear message and when they know what is going on.
