The system is designed to stop one side with a large majority from taking over the system entirely, giving the other side no further hope. With the two sides so polarised, as they are now, and with the "middle" either apathetic or equally split, we have a system where nothing gets done at all.
So I'm going back to repairing my bed - which fell apart again because the screws won't hold into wood that's dried out over 35 years of use - and trying to work out some sort of furniture for a kitchen that is more like a closet than anything else. Americans, they say, are spending less and less time in the kitchen. I'm not surprised! The kitchens these days are too small to swing a kitten in, let alone a dwarf cat!
