Actually, the official WTS position on voting is that the individual jw makes a personal choice not to vote just like choosing not to have a blood transfusion and not to enter the military. The WTS does not want to get into trouble with governments by "telling" their members they can't do these things. I remember during the draft era that the elders were cautioned not to tell young jws not to enter the military.
*** w99 11/1 p. 29 Questions From Readers ***There may be people who are stumbled when they observe that during an election in their country, some Witnesses of Jehovah go to the polling booth and others do not. They may say, ‘Jehovah’s Witnesses are not consistent.’ People should recognize, though, that in matters of individual conscience such as this, each Christian has to make his own decision before Jehovah God.—Romans 14:12.
Whatever personal decisions Jehovah’s Witnesses make in the face of different situations, they take care to preserve their Christian neutrality and freeness of speech.
