Jessica Levinson's post on KCET.org is here.
Here is an excerpt:
"Democracy can sometimes be unpleasant. People disagree. They fight, they argue, and sometimes, they harass. Sometimes it is productive, sometime it is not. Sometimes we find our fellow voters and the causes they support or oppose -- with time or money -- to be repugnant. But our First Amendment stands as a protection for free discourse in a free society, particularly when political speech is involved. When behavior crosses the line, criminal prosecution is possible."
