We recently stumbled upon MyDavidCameron.com
It is a site using crowdsourcing to create their own online spoof advertisements, that then get posted onto the site (as long as they're decent).
The website spoofs the Tory's campaign endline 'Year for Change' and plays on criticism that Cameron's image was airbrushed for their campaign poster. It uses the politics-of-and, which is a form of political airbrushing: you can't cut the deficit and not cut the NHS; you can't cut taxes and have better services (apparently).
