Canceling your registration does no good. Your name and info go into a 'canceled voters' file and is still available to pence/kobach/trump for all of their nefarious purposes.
Canceling your registration, thinking that you can re-register when you need to accomplishes nothing for you or voter's rights but accomplishes everything that pence/kobach/trump/williams want.
Intimdation.
