I finished the whole season now
Let me tell you that it is CERTAINLY back up to the standard of seasons 1 and 2 (better than 3 4 5). It so much more interesting while you following the people going for the democratic nomination. Unless your stupid though, they did not do a good job of keeping you guessing. You should work out who will win pretty early on. Still, its very very very good. Sheen is extremely good as well with the MS.
Leo also has some interesting moments so does CJ and Toby because of something although i cannnot say why without spoiling it
