I will agree to Totnes-style primaries ...

... when the electoral registration process includes the facility for voters to register as supporters of a party in the US way so that:

- supporters of other parties can be excluded from Labour primaries so they can't deliberately back rubbish candidates
- canvassing gets a lot easier because a large slice of the electorate self-canvasses when they register to vote

And when a way is found to square primaries with a role in selections for local party members and affiliates that still makes it worth their while joining (control of the shortlist?).

Oh, and when they are, as in the US, administered and paid for by the same body that runs general elections, using the same polling stations, staff and counting facilities, in our case local authorities, because:

- if the general public want a say in candidate selection they shouldn't expect the party members whose powers they are usurping to pay for it - no representation without taxation
-and unlike Totnes Conservative Association there are hardly any Labour or Lib Dem constituency organisations with the £40,000 to run a postal ballot.
