There is a place to indicate which party you are affiliated with. It is self explanatory if one takes the time to read all instructions before voting. By all means, open your ballot, mb. As I said, I do not know if all Washington counties have this, but Clark County does.
Oh, I was planning on voting. I just wait until election day and drive it to a drop off point. I refuse to mail my ballot in, I am generally not paranoid but just to much could go wrong. Since I live in Clark County, this peaked my interest.
Thanks for the heads up.
