Okay, I get it. He's nervous, his mouth is drying up, he can't get the saliva to form in his mouth. Anyone who's stood in front of a crowd and performed or spoken in public knows the feeling. But why in the name of all that is holy, did he feel compelled to keep eye contact with the camera when he decided to finally reach for the water bottle? And why would his people, or the RNC, or whoever was in charge of this whole debacle not have a glass of water within arm's reach?
Keep going Republicans, you're doing great!
