Madame President. I thought Mellie was going to be a vile sidekick to Fitz at first, but she was the star of the White House. Mellie was so smart and determined for political greatness. She accepted Fitz/Olivia when it was good for her, and did what she needed when it wasn't. Watching Mellie's story-arc from First Lady to President of the United States was the highlight of this show for me <3.
