If we get a chance of getting any proportional system, we need to take it and not insist on perfection.

Yea – but there’s just a few details which mean I prefer MMP!

I have checked and you are right. I would settle for either system.

That’s a common misconception. There’s a couple of important differences between AMS and MMP, to do with i.e. Overhang seats.

They are different names for the same system. Just to be clear, I am referring to the system used in Germany, New Zealand, Scotland and Wales.

…I’m not in favour of AMS, though, I want MMP.

On a more positive note, I am starting to get the feeling that the result in 2015 will be so perverse that any “progressive” government would need to bring in AMS for the 2020 election.

That is why I said claimed. My worry is that the Tories will carry on ruling in a minority or coalition government, while the “progressive” parties just blame each other.

Ah right, so when you launch your coup…
