General Election 2010

Good point, I think you may be right.

1) That isn't actually contradicted by what I wrote :P

2) I still think that this demonstrates traditional Tory values. The message is intended for the Tory base. Strong families, etc etc.

Sure, but it's not a bad message. stable families promote social cohesion, and statistically are more likely to raise better behaved happier children who do better in life. You can see why they'd use the tax system to promote it, as it should result in lower social costs and a net saving.
