Hillary’s Clinton’s microscopic victory in the combined popular vote from last night’s primary–7,347,971 to 7,294,85–fails to take into account the caucuses that were held in Colorado, Minnesota, Kansas, Idaho, North Dakota and Alaska. All of those contests were won–overwhelmingly–by Barack Obama.
Under Democratic rules, each vote isn’t tallied at caucuses. The caucuses serve only to award delegates to go to a state convention (which then elects the national delegates). The results from caucus states reflect the number of convention delegates to the state convention won by each candidate.
So while Hillary Clinton eked past Obama in the popular vote on Super Tuesday, it can also be said that more people who participated in Super Tuesday 2008 favored Obama than Clinton.
