Absolutely pathetic. My pessimism is spiking to C. Derek Varn levels. These motherfuckers have given you NOTHING. They are jingling car keys in front of your face and you are cooing like an infant. How are you not only going to endorse, but TAKE CREDIT for the selection of this guy with absolutely no promises or concessions. This man will be the Vice President, and by your own admission, the blood will be on your hands.
