The one I attended was quite peaceable and non-intimidating. I read on the Lubbock County Democrats Facebook page that some in the area did not attend because of the Hillary-Bernie divisiveness. I saw none of that in person, and was surprised when the county chairperson was announced as a Sanders delegate; his management of the Facebook site showed no sign of his preference.
On Facebook there has been some candidate-bashing, which imo is only healthy, and I've contributed to that.
Attendees at the county convention reflected the vote very closely, about 60 to 40 Hillary to Bernie.
Three of us showed up at my precinct table, 2 Bs and 1 H. I pointed my finger at the Hillary guy and said "You're outnumbered." Otherwise all was cordial, and the other two were named as delegates to the state convention. I wish them a good time in San Antonio.
Good experience, good environment, and I think the tables as opposed to fixed seats contributed to that atmosphere. I am one of those who think that classroom seats, church pews and so on ought to be moveable or in a circle, not fixed facing a podium. (Is it the Quakers who sit in a circle to emphasize that all are equals? Good idea! Respect to my Quaker forebears.)
