Watch this video about the Iowa caucuses and how Iowa voters play an important role in nominating candidates for president. Historically, the Iowa caucuses have served as an early indication of which candidates for president might win the nomination of their political party at that party's national convention, and which ones could drop out for lack of support. Think about the criticism that the Iowa caucuses' role is too important in the early nominating process. Many believe that because its population does not reflect nationwide demographics, it should not be portrayed as an indicator of the types of voters that turn out in the general campaign.
