One thing that irritates me of media coverage of the primaries has been the analysis of exit polling and reporting of demographic trends based on this polling. They all race to announce their guess of the primary winner and then they break down how this race voted for that candidate or how this age group felt about the economy, etc. The naive viewer might assume all this stuff came off the ballots. I never hear mention that this comes from exit polling, the sample size, the error rate of exit polling etc. Curious how serious we should take this kind...
