It never ceases to amaze me how deep racism goes in this country. Listening to News and Notes on NPR the other day I heard a story about a voter suppression tactic that surfaced in low income neighborhoods in Philadelphia. Check out the story in the Daily Pennsylvanian (10/9/08), but in short, "someone" posted a flyer that incorrectly stated that anyone with an outstanding warrant would be arrested when they went to vote. That they targeted low income neighborhoods is a clear instance of the kind of endemic racism critical race theorists talk about.
After digging into it a bit, I found a great wiki that reports and tracks instances of voter suppression for the 2008 election. We've got to keep an eye out! They can't succeed if everyone is watching.
