All of the 13 episodes of the third season of "House of Cards" were released both on Netflix and for torrent download.
Frank has become the President for sure but he did not win the election by votes, he was merely given the torch by the then running President. In typical Frank Underwood style, he first tries to manipulate his own team by saying that he will not run for President in the next term, but he quickly overrides his own words and announces his run for the Presidency. He obviously pisses off many people on the go, but this time, he manages to upset his wife as well.
Claire is not very pleased with his methods and the fact that he wants to take charge all the team and not her get what she wants. She tries to make this right by being appointed as the UN Governor and trying to be someone herself and not just the First Lady, but things are not in her favor after all.
Meanwhile, Frank hires a writer and he wants him to write a book on his program "America Works", but the writer ends up digging Franks and Clair's stories and the book becomes personal, rather than political. Claire is not very pleased with this and she dismisses the idea altogether. Also "America Works" is a trademarked term and the original organization isn't too happy about their brand name being used without permission in the popular show.
Also, Doug has fully recovered from his almost fatal accident and is after his previous job, he is as loyal to Frank as he always was, with his own twisty methods.
