Unbelievable, just watch and wait for the Voxpops and see how each "ordinary person" is described.
Alternatively, if you can't be arsed to watch it, you could just watch this amusing video that has appeared on YouTube and edited by a user called not winning here and just shows you the best bits!
Startling honesty from the Lib Dems there. Another day, another gaffe!
Update: Just in case they remove the original you can download the flash video here
