I'm watching Season II now (thanks, Niall) and I thought that there was one line in the 2nd episode (I think) which really summed up the series. It's a flashback to the campaign to become president. Jeb's not sure about it but Leo is and he says "You know that they say that a good man can't become president. I don't think that's true." And that's what the show is in a nutshell. It's the fantasy where Leo is right and a good man and a bunch of idealists can make it to the White House. It's sweet, and I'm still loving it.
