12. How it worked in my precinct

Groups formed; viability threshold of 15 percent of total registered attendees was determined; headcounts in each group took place; preference cards, each uniquely numbered, were distributed with instructions DO NOT SIGN; opportunity was given for anyone to change their mind and realign; groups offered speeches to persuade uncommitteds or nonviables to realign to another group (effectively, if one group was a few people short of viability, soft supporters in other groups that were viable could defect); cards were signed and the attendee became locked in. Final counts were based on signed cards (the "paper trail&quot , those were collected and all accounted for; delegates were awarded to viable groups according to formula; those delegates and others from other precincts in the county will meet at the county convention in late March; the process then transitions to district convention, then to state, with viability of preference groups determined along the way. Interestingly, my preference group chose as a delegate an attendee whose group (Tom) was not viable and who joined us.

I think Claire is a bit confused, but who isn't??!!
