The behaviour of politicians is usually revolting and their actions in trying to hide their expenses behind an exemption from the Freedom of Information Act is more than usually stomach churning.

This is a black and white issue. Honest people respond by saying "No". Anything else is just another way of admitting that you're a crook. David Cameron responds by saying he's neutral. This tells us something about him. Either he doesn't know right from wrong, or he has good reasons for tolerating a certain level of corruption among his MPs.

It also tells us that we shouldn't under any circumstances, vote for him or the pondlife that surround him.
