For the millions of people watching Rubio's nationally televised remarks on Tuesday night, it wasn't so much that the senator was cotton-mouthed as he offered the GOP's vision on the economy. It was the way Rubio a young, charismatic politician mentioned as a future presidential hopeful quenched his thirst.
Rubio was standing in front of a TV camera in one of House Speaker John Boehner's conference rooms at the U.S. Capitol as he delivered his remarks. An 8-ounce bottle of Poland Spring water was out of view on a table, and he stepped out of the shot for a moment without taking his eyes off the camera to take a sip.
Rubio took a bottle of water to some of his morning show interviews, playing along with the joke as he took a swig while he was on Fox News. It was a step beyond what he did after his speech, when he posted a picture of an empty Poland Spring bottle on Twitter.
"When you give a speech on a podium and the water is right there. But when you don't, you start looking around thinking, 'Where am I going to get the water?'" he said on Fox News.
Rubio explained on CBS that he had a long day. Before giving his speech live in English, he also taped his remarks in Spanish marking the first time in history that the State of the Union response was delivered in two languages.
"I had already taped an 18-minute speech in Spanish," the senator said. "So I'm just glad the water was nearby. I don't know what I would have done without it."
In politics, the ability to poke fun at oneself is a critical survival tool. Texas Gov. Rick Perry appeared on late-night TV shows after he uttered "oops" during a GOP presidential debate in 2011 because he could not remember the name of a federal department he wanted to cut. Perry, whose presidential campaign was already struggling at that time, also walked into the media spin room immediately after the debate to tell reporters he "stepped in it."
New Jersey Gov. Chris Christie got into it, too, during a recent appearance on David Letterman's Late Show. Letterman likes to make fat jokes about Christie, so the governor took a bite out of a doughnut as he was being interviewed.
