That the membership should not be able to vote for candidates?
You are not advertising centrism very well tonight.
It's too open to entryism. It's a free-for-all. And you know it is, deep down you do, you just won't admit it.
There's honestly no difference between the Tories allowing white right wing nationalists to join en masse and have the power to put in a Tommy Robinson. You're never going to have a counter-balance of half a million centre-left people join in the same way as they simply don't mobilise in that way, but the country by and large is moderate in their political views.
So you have a membership who in no way reflect the mainstream, dictating the direction of a party who is meant to try and gain power by attracting mainstream votes!
The old Labour leadership rules accommodated for steady swings in view - for example, Ed Milliband; he came to be leader because the party as a whole had edged left after the Blair/Brown years, and rightly so.
