Phillip Moss, 84, and Jennifer Hill, 38, are both facing charges.
Moss is accused of voting twice - once in person in Florida, and again by paper ballot in Pennsylvania.
There's a warrant now for his arrest.
Hill was arraigned this morning on dozens of charges.
Prosecutors say she led a months-long effort to fraudulently register voters, including people she knew were dead.
DA Jack Stollsteimer says she was employed as a canvasser, and did it to appear successful to her boss.
