CNN Student News is back for 2012 and this morning’s episode is about the Iowa caucuses and North Korea. The bulk of the episode is about the caucuses, why they are important, and why the primaries later in the month are important too. The video is embedded below.
I did a quick search on YouTube for some other explanations of caucuses and came up with this video from CBS News.
Here is an explanation of the caucus process according to Sky News.
CNN also has this video explaining why Iowa and New Hampshire go first and matter.
