Love Homeland.
I have a feeling Brody will become the VP. The president will be assassinated and just like Johnson, Brody will become the President. Then watch out.
Your theory seems less likely after last night's episode.
Carrie needs to be brought back into the plot somehow. The only way that can happen is if it's shown that she was right about Brody all along. That is now possible ...
Daniel Lewis has signed a 5 year deal so they obviously have fairly complicated plans for him. I too think that ultimately become Pres, a bit of Clancy there. I'm still not convinced that Estes isn't a mole, the Americans like to use a British actor for someone who will be unpopular with the American viewers! Both He and Saul actively interfered with Carrie's investigations in Series 1. I need to get out more.
