Actually, I'm doing an interview with a right-wing newspaper this week, which normally isn't my thing, but they did a piece on this and they made a very good point about the factual inaccuracies. TPM and AOTC were both written and filmed before George Bush was ever in office. Lucas has admitted that any similarities to contemporary politics in those films is coincidental, as the only American politics those films referenced was the Nixon administration, and that was just one source of many (e.g. Julius Caesar, Adolph Hitler, etc.). ROTS tailored itself to the politics of the time, but only a little, as the story was already in place by 2002 and the writing was begun before the war in Iraq existed.
