As primary elections are taking place today in nine states including the District of Columbia, voters should pay heed to the various voter identification efforts throughout the country. The LA Times today put out a very helpful and comprehensive story on these cases.

Among the primaries today, Arizona's election today will test Proposition 200 that now requires identification when voting. azcentral.com has this story.
