In some key battleground states, the number of eligible but unregistered Latino voters runs into the hundreds of thousands or even millions. On top of these millions of potential voters, the Department of Homeland Security estimates that there are 8.1 million legal permanent residents, or green card holders, that are eligible to become citizens and vote in the fall election.
This interactive map looks at the top 10 states with the highest number of potential voters, comparing the number of voters to the margin of victory (the number of votes by which either candidate won each state) in the 2008 presidential election.
In California, Texas, Florida, Arizona, Colorado, Georgia, New Mexico, and Nevada, the number of potential voters is greater than the margin of victory, while in New York and Virginia, the number is close to the margin.
