I thought the episode on Monday night was GREAT! Especially the part where Walt is getting pummeled by Jack. :)
It's not Walt Cummings who looks like Nixon. It's the President. And you gotta admit, he DOES look like Nixon. I was getting a whole Nixonian vibe off of him every time I saw him.
Re-read the sentence One of the moles in this season is this goofy Richard Nixon look-a-likes chief of staff, guy named Walt Cummings.
He's not saying the chief of staff is a Nixon look a like, he's saying that POTUS Logan is the Nixon look a like.
Rush didn't say that Walt looked like Nixon. He said that the character of the president looked like Nixon (and he does - my wife is tired of me mentioning it every time we watch it).
