Asking us to accept Yvette as an alternative to Harman is a false dichotomy too far.
It is like being threatened with having to muck out a dog kennel with your bare hands and then someone running up cheerily with the alternative - to muck out the cat cages instead. And the cats have the squits.
NO NO AND THRICE NO.
Both of these USELESS people have been utterly destructive to the Nation for over a decade. I would not trust them to grab their own backsides using both hands in broad daylight with the use of a mirror*. Yvette seems incapable of answering questions, listening or communicating in a sensible way. I don't care if she appears clever - she might be the smartest person in the room, but look at the others in that room (the cabinet)!
In some ways it would be interesting to have a 2 Ball race, or a race with two Balls in it at least. Would make a change. Maybe that is the real agenda here - Mrs Balls acts to help secure the post for Mr Balls.
Personally, I think the up-coming election failure for Labour will see a split, or should I say Social Democrats going to the LibDems and Labour becoming more openly Socialist again.
* that might suggest that I consider Harman to be potentially even more stupid than Cooper, but I shall not comment on that one.
