If the Chopey chump chappy doesn't predict that - his bill is dead in the water

That makes the assumption his aim is to get the bill passed. Politics can be much more subtle. His aim may simply be to get talk of paying for the NHS normalised.

There is a film Dirty Pictures which is about a court case brought by a right wing Christian group against the Cincinnati Contemporary Arts Center for exhibiting Robert Maplethorpe's photographs, which they regarded as pornography. At the end, the gallery won the case, and an interviewer asked the group how they felt about losing. The response was something like "We didn't lose. No gallery will consider exhibiting photos like these in the future because of the costs and damages it will incur. They will play safe. So while we lost the case, we have achieved our objective."

It's a thought provoking film, and I recommend it. And it seems to me it is the same kind of thinking in the NHS bill. Whether it wins or not is not the primary objective.
