Guys, just so you know where I'm coming from, I'm a Republican and a right-of-center conservative. I listen to Limbaugh, I voted for Bush twice and glad I did.
At the same time, I don't feel that much concern here, mostly because, as a Star Wars fan from the early days, I pretty much expected what had to happen here: in order for there to be an Empire, the Republic had to die. We knew that Palpatine was going to do what he did, and how he was going to do it. It was in the prologue to the novel of A New Hope, it was in numerous RPG books - though in abbreviated form, to be sure. I knew what was coming for twenty-two years; it was written in stone long before George W. Bush had political aspirations. It's no biggie.
That said, I think the little in-jokes you can read in both Labyrinth of Evil and the Revenge of the Sith novelization are kind of loaded. I mean, the Department of Homeworld Security? An Empire ruled by the majority? Come on. They're sublte, unsubtle, or just plain cute references to current events.
I would be worried, if, in LOE, Palpatine didn't view the Constitution as a living document - his justification to change it to suit his Imperial desires. But he did say that to Bail Organa in that book. The reason this disarms my feelings is that this refers to a liberal issue. Conservatives are often strict-constructionists when it comes to the Constitution, and aren't necessarily up to viewing it as a living document, a thing that changes with the times.
What does this mean? As far as I can see, I think the folks at Lucasfilm are just making jokes, trying to be cute. They're not trying to offend me, and I'm not offended. They're not making this a strictly conservative or strictly liberal issue, they're using the language of our times to make the events of the Galaxy Far, Far Away more easily understood by us, the planet-bound simpletons.
As far as Lucas' personal politics are concerned, I'm not sure I can say with any certainty what they are. He never really bothered to advertise them, and his words at Cannes could easily be something the foreign press chose to focus on in lieu of other subjects Lucas brought up. I have been reasonaly sure he was a left-of-center kind of guy, someone who didn't care for Vietnam (he's spoken about this a few times), and someone who definitely didnt care for Richard Nixon (he's spoken about this, too). But he's not Michael Moore, for crying out loud!
So I'm going to invoke the "Can't We All Just Get Along" argument and relax. All's I know is that in an hour and a half, I'm off the the theater! Politics end when the Fox logo pops up!
Good night, and my best to you all.
