Season 4 of House of Cards might see Frank Underwood (Kevin Spacey) up against more than he is capable of handling.

Release Date Pushed Back To Align Show With Presidential Elections? 

A new report hints at the possibility of his old enemies returning to engineer his downfall, and some of them will be doubly charged with this motive. The report specifically cites Remy Danton (Mahershala Ali) and Jackie Sharp (Molly Parker) as pairing up to weaken Frank's poise.

There are many doubts about is Frank will be able to stand resilient through the next chapter after the grave hit he took in season 3 with his greatest supporter, Claire (Robin Wright), leaving him. Meanwhile, there has also been speculation of new characters entering the arena to take Frank down. Two new additions to the cast of House of Cards had us wondering if they will help anatagonize Frank some more. One of the major stars being brought on board for the next chapter is Neve Campbell. Deadline had hinted that Cambell's character might rival Frank in season 4. This fits in with another spoiler relating to a younger power couple being introduced in the Netflix political drama. Could Campbell's character be one half of this power couple?

Old enemies and new ones might really push Frank to the edge, and maybe over it as well. Unless of course Claire changes her mind and for some reason returns by the presidential hopefuls side to empower him again.

Season 4 is set to return in 2016.
