Frank Underwood is one of the more Machiavellian characters on television today, or in this case, on Netflix. He starts out as a Democratic congressman from South Carolina and spends the series trying to weasel his way into positions of greater political power.
Underwood's dealings are instructive for any current or aspiring business leader, since they show the importance of treating your subordinates with respect (which Frank doesn't) and bouncing back from setbacks (which Frank does).
It's also a lesson in how to manipulate people and trade favors to get what you want. As writer and creator Beau Willimon told US News: "To be effective leaders, you often have to do things that are morally abhorrent to the rest of us."
The fourth season begins in 2016.
