Malfeasance by election officials, acting “under color of law,” such as diluting valid ballots with invalid ones (so-called “ballot box stuffing”), rendering false vote tabulations, or preventing valid voter registrations or votes from being given effect in any election (18 U.S.C. §§ 241, 242), as well as in elections where federal candidates are on the ballot (52 U.S.C. §§ 10307, 20511).
