Dubious exit poll practices

Exit polls too often only ask Republicans about their religion affiliation and only ask Democrats about union membership.

Do TV ratings depend on telling a meta-story of an America divided into two completely separate cultures or something? Why do they run their polls this way?

Good questions. Because such assumptions aren’t valid.

Large numbers
of white evangelicals participated in both parties’ primaries; majorities want a broader agenda that goes beyond abortion and same-sex marriage, and white evangelicals ranked jobs and economy as the most important issue determining their votes.

They have a initiative, Faithful America, that requests the practice of pollsters only asking religious questions to Republican be stopped.
