This is really good! I like big innovations to democracy, but these are few and far between.
The party becoming mostly as a mechanism to nominate people is a great use of societal resources. This takes any collective ideology out of the decision-making process, allowing elected representatives to vote on legislations without party considerations.
When the ideas of the TDG first came to me (1992), they were pretty jumbled. It took the third edition and 17 years to finally get all the TDG pieces together.
One concept I toyed with for a long time was the "constituency." Most of us have more commonality with people outside our immediate geographical area. So maybe these farther-flung communities should form the basis for our vote. For example, I was an oilfield worker when the TDG came to me. There was not any mechanism for these workers to send "one of them" into the legislature. But after a lot of thought, I went back to geography as the means to organize the TDG elections.
But this does not mean the early TDG builders have to stick only with geography. They just might want to add a caucus approach to their elections. I can see this being possible when much of the energy spent on electioneering is no longer needed yet needs to go somewhere else.
