Well, when the budget was read out I did say some of the turkeys who voted for Christmas would get a shock when they realized it. I didn't take any pleasure from watching her, but she is one of the people who helped us into this very situation. Wanting the Tories to go after benefits claimants and then getting upset at the bombshell news that they actually are considered benefits claimants.
I don't recall the Tories saying that tax credits were safe, and I do remember more savvy posters than me speculating before the election that some of the huge amount the Tories wanted to cut from the benefits bill would have to come from tax credits.
Ultimately, if you're going to vote for a party that is full of the rich and privileged, and doesn't even bother to hide the fact that their priority is in looking after the rich and the privileged over anyone else, it's sensible to make sure you're not vulnerable in anyway first.
I do hope more people like her come forward - there is time for Gideon to announce some kind of buffer, but unless there is a very noticeable public outcry - why would they bother?
