Just chiming in to say that a good American political satire is Veep, on HBO. If you enjoy that sort of thing, check it out.
Anyhow, I like your idea. I enjoy politics and political stories. While Transformers (as a kid-oriented franchise) will likely never venture far into that territory, if it did your "Starscream as politician" idea is a good one. He does have a lot of the stereotypical character flaws that people associate with politicians... arrogance, cravenness, opportunism, disloyalty, etc., but with just enough smooth-talking charm to keep himself in a leadership role.
Thank you for the recommendation and for liking the concept.
i like my megatrons, optimi and starscreams all around the same general height. i still can't find an 'excuse' for all the mass shifting going on in G1 but in other continuities (especially movie) i like to pretend megatron had some suspicions about starscream and forced him to get some kind of body mod or something that makes it where starcream's body is forced to shrink in robot mode, no matter how massive his alt mode is. of course starscream is the only aircraft we get a leader for, dang it. i would kill for a leader rotf mindwipe.
