Assuming you are being honest and forthright, you have either never voted because no candidate has ever met your standard of ideological purity, or you used to vote but stopped doing so for one reason or another.
Perhaps you joined some religious group that doesn't believe in voting but can't quite bring yourself to disclosing that to us.
No baby killing, that's right out.
We keep our guns.
No socialized medicine.
Keep government small.
That's pretty small beans on purity, Flight Service Officer.
