At the very apex of power, who will F. Underwood connive and cajole? He has no superiors to deceive and manipulate.
My guess is that it'll be either Congress or the Supreme Court? Getting his way with the judiciary would be very very interesting...hmmm... (I wish we had a thinking emoticon right now..haha)
Besides, I'm sure the liberal writers wouldn't pass up the opportunity to make fun of conservative justices.
