It's not "partisan" unless it specifically involves one of the two parties, or a candidate thereof. There's the loophole.

My advice, If you do know people at LucasFilm, get on the horn and stir some shit up. They're probably not even aware of it. It will probably do more good than a torrent of letters from angry fans. After all: They brought Jar Jar Binks back for the last two movies, right?
