The recall process is similar to the initiative process in that citizen petitions are required. The number of signatures necessary to qualify a recall petition, however, is often significantly higher than for initiatives. Signature requirements are based on a formula, generally a percentage of the vote in the last election for the office in question, although some states base the formula on the number of eligible voters or other variants. Whatever the formula, the signature requirements are high: 25 percent in nine states; 25 percent for statewide offices and 35 percent for legislators in Washington; one-third in Louisiana; and 40 percent in Kansas. California's requirements are 12 percent for statewide offices; 20 percent for legislators and appellate judges. Georgia requires 15 percent for statewide offices and 30 percent for all others. Idaho requires 20 percent for all offices. Montana has the lowest number of required signatures: 10 percent for statewide officials and 15 percent for state district offices such as legislative districts
