RRNYC, I do not dispute the experience you had may have shown some of his supporters out of line. It does reflect poorly on on those individuals at the caucus, but it does not diminish the strength of his grassroots organization. To me, there is a distinction. I'm sorry you felt intimidated by obvious neophytes abusing tried-and-true caucus tactics. Obama has drawn a lot of newbies. Do not judge the man by some of his over zealous supporters. I'm sure he would repudiate the misuse of those tactics.
MOST people signed and left. It was so unorganized! When they were counting Obama supporters, a Clinton supporter started counting too to confuse people and have them not be counted. Not to mention, the polling place was changed at the last minute without any kind of notice. The only way I realized that they changed it was the second location was my little sisters elementary school. There were so many problems.
