Poor polling practice

I hope no one takes the results of this poll by the Conservative party very seriously. Before they even collect results, I know that those results will have significant bias.

  1. They promoted their own political party in large bold font just before their survey question. This is equivalent to saying "Chocolate is AWESOME!! Do you like chocolate, yes or no?"
     
  2. They are relying on people to take the time to respond to the survey themselves, which suggests that they will end up with a small group of people who are die-hard opponents of the Conservative party, and probably a larger group of Conservative party supporters. Who else would bother voting in this poll?

Note: If you were to substitute any other political party into this poll or a similarly run one, it would be just as invalid.
