He's referring to the vortex that sonetimes occurs when water flows down a drain.

He is comparing the politicians' views with the contents of a sewer. They have similar views so it is the same sewer. It isn't an expression that I have come across before.

I think it is another way of saying the derogatory term "talking sh*t (sewage)* without being explicit about it. It means talking nonsense and lying. The politicians' replies to the rising cost of living were rubbish.
