They're not a Trojan Horse. They're just the Trojans, they knocked on the gates and said "yes hello we would like to come in to rape your women and children, pillage your valuables, and destroy the city."

Maybe the way forward for election reform is to put it as a footnote in a proposition declaring murder to be bad.
