On the day of the Iowa caucuses, Republican presidential candidate Marco Rubio said on TODAY that "we're not the front-runner in Iowa" but adds that he feels "positive" about his prospects.
"We feel good about our campaign, we know it's an uphill climb but we are fighting hard, we're working hard, we're growing every day in the support we have and I feel really positive," he said.
Rubio says that Republican presidential candidate Ted Cruz edited a video to make it look like Rubio supports cap-and-trade, and called it "unfortunate." "It's the politics as usual and that's the problem," he added, "When you wait to the last minute to attack someone on something, it's usually not true, that's why they waited til the last minute."
Saying he's "not a political analyst," he declined to predict the outcome of the caucuses. He calls Donald Trump "a very good entertainer" but says that he needs to explain how he plans to accomplish goals like defeating ISIS.
