Push polling

I did an opinion poll this morning.

I'm registered with YouGov a UK opinion poll service and get occassional polls sent to me - they have either a prize draw or a 50p (NSD1.45) bonus attached, as well as sometimes being quite interesting.

This one was in the latter category:

They started out by asking various questions on identity theft: had I been a victim of, were the banks/government/telcos doing enough to prevent it, did I feel confident with internet shopping, etc.

After about 5 questions of this nature, they had one similar to this:
Select one or more of the following:
- I think ID cards will help reduce identity theft
- I think ID cards will make banking more secure
- I think ID cards will help combat terrorism
- None of the above

Now, for those who don't know, one of the many illiberal measures being brought in by the UK government is a mandatory ID card scheme. I strongly suspect that the above poll was commissioned by the very same UK government. A poll like this is called a "push poll" - the idea is that the preceding questions put an initially undecided subject in a frame of mind to give the "right" answer - which in this case can be headlined as "XX% support ID cards - poll" where XX% is all those who didn't answer "None of the above".

I wonder how many of the "impartial surveys", both in the UK and NZ, are in fact organised along these lines. (YouGov is regarded as a reputable source - although I and others have doubts about their methodology of taking a self-selecting minority of internet users and then adjusting the figures to correct for sample bias).
