OK, after a lot of people commented, I ran a brief analysis of the thing. I wrote it up here
: Now copying and pasting in here below so I've got the analysis, 19/1/2008].
I've put a Tab Delimited Text file up on my storage site
(for those not used to TDT files, open with a spreadsheet or database programme like excel, and re-display the columns. Excel filters then let you choose parties and their preferences).
Essentially, many of the policies chosen are popular (or are supposed to be) LibDem policies. But the Labour policies chosen are not that popular, and not what they're really campaigning on. UKIP gets its two main issues easily highlighted at the top (for those curious, if you put in a neutral result for the two Europe Qs, but are opposed to, for example, ID cards, you're likely to show a soft positive for UKIP. Tories also get a number of their headline policies.( More detailed analysis )
So, the test, while fun, is unlikely to show you as a Labour supporter, and is very likely, if you're on the "left" to show you as a LibDem; 3 of Labour's 7 positive areas are also LibDem areas.
Is this a problem? Not if, like me, you're actively out campaigning for the LibDems. But if you want an impartial way of finding out who you should go for, one that allows for choices on all policy issues should possibly be chosen.( Remainder of original post )
