A quote from December 2019 / January 2020 Philosophy Now which quotes it from a greeting card (no source of the card given):
Politics. Noun. From the Greek poly meaning 'many' and ticks meaning blood-sucking 'insects'.
Further down in the article - Into the Cauldron" - the author suggests the 'many' cast out the 'ticks' and vote for themselves a new batch of constituents.
Nos dawch, everyone. Hazel
