To be honest, I actually think that's a decent reason, for those on the left, to take a bit of solace in the current government
If the Taxpayers Union thinks she is too moderate, then centre / left voters shouldn't be too disheartened that she's there. Which *should* be a better outcome for those voters than if the TPU got its way
If the government sticks it out with Willis, we'll continue to get boring but moderate policy enacted, rather than a hard swing to the right. Which in my view would have more legs in it than a liberal alternative
