I wish Ryan showed some assertiveness against Biden every time he would interrupt him or laugh at him...and likewise show some backbone to the moderator (an Obama friend..she invited him to her wedding), when she would gang up on Ryan.
A simple, "Excuse me, Mr. Biden. It's my turn to speak and I would greatly appreciate it if you show me some respect because that's how I intend on act towards the moments you speak irregardless of how ridiculous you sound when you debate."
