The Pew Charitable Trusts released a nifty interactive report this week that compares the 50 states and the District of Columbia on their administration of elections.
Pew gathered information from the Census Bureau, public surveys, and other sources to develop its Elections Performance Index. So far, the data is available only for the 2008 and 2010 elections, but it makes clear that the security of your voting rights depends heavily on where you live.
