Rubio on Jeb: We’re Going to Continue to Run an ‘Optimistic’ Campaign

KING: "Senator, I was at the dinner last night in New York and a lot of your supporters were giving you a way to go for your commercial before the debate where you have Jeb Bush praising you. My question is this. What is your strategy there and what is your relationship like with Jeb Bush?"
RUBIO: "Well, no. Look, I am close. I mean, I admire him greatly and have tremendous respect and affection for him as a person. Unfortunately, over the last few weeks, he has chosen to attack me but I'm not change my strategy and reciprocate that. I'm going to continue to focus on the future of America and I'm not going to change who I am or the campaign that I'm running because of someone else's strategic decisions and changes in their campaign. I hope -- we are going to continue to run a campaign that is realistic  about our challenges and optimistic about our on opportunities and our future. I think ultimate that is the way to win this nomination and be elected president."
