I usually don't post links to interviews with people other than Jamie, but Ron Moore, in an interview with MediaBlvd, addresses a few questions related to Lee and I found his answers to be very interesting. The full interview can be found here. While Ron gives some intriguing hints as to what we will be seeing in the final eight episodes, there are no significant spoilers.
You've introduced many plotlines around for Lee Adama, some of which worked and some of which didn't. Is there anything you can spill on Lee's character arc? For example, the impact of his new political role on his relationship with the dying president, Laura Roslin?
RDM: I think Lee has found his true path (and so have the writers). His role as leader of the civilian government will become even more important in the second half of the season and Lee will provide a key idea in the final episode that brings the show to its conclusion.
There were many fan complaints throughout season 3. For many, the show just died and went to shipper heaven with the infamous Lee/Kara/Dualla/Anders love quadrangle. The demographics of the BSG online fanbase has certainly evolved since 2003 - there seem to be fewer generalized SF fans and more "shippers". From one perspective, it more resembles Roswell fandom than Star Trek fandom. How do you draw the line between character-based drama and soap opera? Do you see a downside in your approach?
RDM: I don't really draw those kinds of lines, I just try to go where I think there are interesting stories to be told. I think that problems with the Lee/Kara/Dualla/Anders quadrangle were matters of execution (on the page, not on the set) rather than conceptual. I liked the reasons why I went in those directions, but just didn't plot and write the story arc in a way that was satisfying.
In previous interviews, when asked about the softening of the ratings, you've answered that you were happy with the creative choices that you've made, and that those choices were story-driven and that this series is being made the way you want it to be made. Now that it is nearly over, can you say that there were places where you should have maybe turned left when you turned right? Would you have done anything differently if you had to do it all over again?
RDM: Again, I'd say that the romantic relationships with Lee et al could've been handled better and I wish I had locked into the political path for Lee much earlier, but by and large I'm happy with the choices I made.
I'm thrilled to read Lee plays a pivotal role in the finale. On the other hand, I'm perplexed that Ron didn't put Lee on the political path earlier. It seemed apparent to most fans very early on that politics was to be Lee's true calling.
