Based on the season finale, Claire Underwood will eventually evolve to become the villain in Season 4 of “House of Cards,” which was already expected by the show’s legions of fans. Given her position in the White House and what she knows about Frank, Claire has all the goods against the president to ensure his downfall.
But instead of plotting his downfall via political maneuverings, apparently journalism and media expose will do Frank Underwood in especially in the eyes of the American public and serve the justice that needed to be meted on him for his shady past as well as wheelings and dealings.
As Constance Zimmer is a journalist herself, this is where her role plays an important part in the downfall of Frank. Other than those key plot information, there are no further details with regards to the upcoming Season 4 of “House of Cards,” as the production company wants to keep a tight lid on information until production for the fourth season begins.
