First up we have Is your Cat confused about the referendum on the voting system on the 5th May? With cat versus dog simplicity, some nifty graphics, and why AV keeps out the nasty dogs. It’s even good at explaining AV!
Second we have Does she know what she’s talking about? – a baby with an odd laugh and whose words supposedly lead to the conclusion that because she wants No, you should vote Yes. Low on nuance, high on oddity.
Last there’s Dan Snow’s Alternative – the most serious of the three, but a neat explanation of why AV is a step in the right direction, using the analogy of whether to go to a pub or a café.
UPDATE – @sunny_hundal suggests The Alternative Vote Explained. It has 100k views and has nice graphics, but it’s not as amusing as the cats video.
UPDATE 2 – Seems I’ve started something here, for @speckl now suggests @MJHibbett‘s home made song I’m Saying Yes, with Ed Miliband and Vince Cable on guitars.
