So what?

• Two separate, meaningful factors
• Both can be described as "left/right", but they are quite different

• First is much more important and has little to do with economics or Iraq, and a lot to do with immigration, law-and-order, etc. etc.
• First axis separates Labour from the Tories
• Second separates New Labour from Old (roughly)
• No particular clusters: distribution is unimodal on both axes
• ... but that's what we expect from this method anyway

• Parties can't compete much on values (to the extent that they express their supporters' values)
• ... they're already fighting over the same space
• Fringe parties are not so much on the fringes as mixed up in the whole lump

• What determines the fraction of people at a given value of x who vote Labour and which Lib Dem?
• Comparing supporters of two parties on any given part of the plot doesn't reveal organised differences between them in terms of these questions
• ... there may be other, demographic differences — I haven't had time to look at these yet
