Specifies the temp, asks for a few bottles of water and wants the TV on, so what? The man's the VP of the world's only Hyperpower. Ever see a pop star's rider of what they 'demand'?
He's not asking for a gift, they want to know if any item is going to be placed in his room - security reasons.
I know it is crazy for them to continuously complain about these little requests. The press already said that the Vice President can not compare himself to the pop star's because tax payers don't pay their bills. But even still, these are extremely normal and you are right that security is needed to be first.
