When your turn to meet the Senator comes, you'll hand your voucher to an event representative who will hand Senator Clinton the book. Once signed, the book will be handed to you.God forbid a mere commoner be allowed to hand his/her book directly to Her Royal Heinous, The Hildabeaste.
There will probably be a Hildabeaste Goon with a bullhorn yelling, "Approach her empy-handed!"
"Hey you! Put down the camera and back slowly away with your hands held high!"
Sure wish I could puke on command.
