In this NEED TO KNOW Election 2012 special, Maria Hinojosa visits one of the country's most surprisingly diverse communities, a home to residents from more than 40 countries who speak more than 60 languages and dialects. Clarkston, Georgia, a town of 7,500 people, was 90 percent white in the 1980s; today, it is less than 14 percent white. The program looks at how a rising multicultural population may influence American culture and affect the 2012 presidential election.
