Sith Interceptor contributes this report about a key scene in Episode II. Spoilers ahead, so don't highlight the space below if you want to be surprised in 2002:

In Palpatine's office, a small group of dignitaries form a secret meeting. Bail Organa, Orn Free Taa, Jar Jar Binks and Chancellor Palpatine are just some of those present.

The senators squabble and debate the possibility that "emergency powers" be given to Palpatine, greatly increasing his power during the conflict with the separatists. With Palpatine subtly goading the issue, Jar Jar speaks up and elects himself to raise the issue at the next senate hearing. This is not a spur-of-the-moment decision for Jar Jar, and really shows his maturity, and that he wants to do his best to ensure the well-being of the Republic. Unfortunately, Palpatine has manipulated him, and Jar Jar is helping his more sinister plans. At this point, I feel the audience will feel sorry for Jar Jar... even those who already dislike him.

One big step in Palpatine's path to becoming the Emperor.
