Essays / 'Democracy and Rhetoric' - What to write about?! [3]

So I've been set an essay to write, of about 3000 words, entitled 'Democracy and Rhetoric' and have also been given a booklet with 9 speeches in it, ranging from Pericles funeral speech in 431BC to David Cameron's latest speech. I have been told I can write about anything I like, as long as it fits with the title, any ideas?!
