Bad news for the economy this week, but good news for the manufacturers of Red Bull, Absolut Vodka and Valtrex: that’s because it’s Spring Break again. That magical time of year when American college students descend on South Padre island and Cancun, Mexico to really immerse themselves in local customs, like tequila body shots and wet sombrero contests. But while you and many more age-appropriate partiers are on the beach, there’s a small group of students devoting this Spring Break to a more political kind of partying. They’re using their vacation days to volunteer for their favorite presidential candidates.
