while i don't agree with everything in 'freakonomics', the link between abortion, and less street crime, is interesting.
if there were more abortions (according to freako), then there would be less children born into poverty, particularly to young (vulnerable) mothers. there would then be LESS children growing up in difficult situations, turning to crime, getting asbos etc etc. AND less people to vote against the Tories. You'd think they'd be encouraging abortions, particularly amongst 'certain' types!
(nb, v tongue-in-cheek about this, but there are stats to show abortion helps to reduce poverty, and indirectly, certain kinds of crime)
