Lyon says she left the meeting "upset and angry," calling it a waste of time.
But Parker says the meeting was, in fact, run in an open and fair manner. He says it was advertised publicly and some 40 registered Democrats attended, as well as a few observers.
He adds that members of an "opposition group" also attended.
According to Parker, a slate of candidates was put forth, and a member of the caucus suggested the committee vote to adopt it.
"And it was pretty clear that the folks who came in to try and push some other agenda through didn't have the votes to do it," he said. "That was the up or down vote - nobody was disenfranchised, everybody got to vote that was a registered Democrat according to the Board of Elections list."
"We had about 13 people voting no, and between 26 and 28 people voting yes, and that was that," Parker added.
Parker says that anyone seeking a nomination that had enough votes could have gotten on the ticket.
He notes that advance publicity of the meeting and the high turnout speaks to the "democracy" of the caucus.
