VIDEO: History of Super Tuesday

NBC's Domenico Montanaro reports on how Super Tuesday became so pivotal. It all dates back to the 1980s when Southern Democrats were upset with liberal presidential nominees. They wanted to nationalize the message and lessen the impact of early caucus states like Iowa. Instead, today's presidential candidates have to run essentially national campaigns from the day they announce.
