Bad Satire or Shaming the Opposition

The campaign for an English Parliament, equivalent to those of Scotland, Wales and Northern Ireland, is worthwhile and perhaps there are elements of the video that could be perceived as fair comment, but are the cheap shots necessary or effective. While calling John Prescott a 'Vast Waist Of Space' may work for Private Eye is it right for a political campaign video? Or does it make it engaging? The curious bit for me is the choice of music 'Cap in Hand' by The Proclaimers; while the sentiment "But I can’t understand why we let someone else rule our landWe’re cap in hand" may be felt by English Democrat supporters it could be perceived as essentially anti-Westminster if not anti British/English. But the main feature is the slideshow presentation of current politicians attacking them, does this work and why.
