If they persist in trying to avoid their constitutional responsibilities and exercising them to the fullest extent possible, then their negligence will lead others to conclude that the entire system is nonfunctional, totally incapable of exercising the will of the people let alone the precepts of constitutional law, and there will be acts of vigilantism filling the vacuum they left...giving Obama and the rest of Team Evil the very pretext they need to officially sweep away any remnants of republican government. But apparently they are completely unable to see the big picture so whatever happens is going to have the full appearance of inevitability.
Oh well, SSDD, see you on the other side!
