Post Black Panthers at polling stations to ensure voter integrity.
What? They did that once and it failed?
Never mind.
From http://en.wikipedia.org/wiki/New_Black_Panther_Party_voter_intimidation_case :
“No complaints were filed by voters about the incident, although poll watchers witnessed some voters approach the polls and then turn away, apparently in response to the New Black Panther Party members.”
If so, it didn’t fail.
