House of Cards gave a pretty good look t what can happen at a brokered convention. I hate to recommend this show because of the gratuitous sex scenes, but the inside look at the scum we elect to rule over us is well worth the time to educate some of your less informed friends.
I wish they would let us have the Airline versions, in fact I wish they would offer the TVMA versions edited down to at least TV 14 which is still pretty vile.
