No sure why, but as one on SCOTUS once said re:porno, their recognition of it, shows it exists.
"Teacher Alleges Intimidation at MA Polling Place January 19, 2010 LAWRENCE, Mass. Minutes after the polls opened at Guilmette School here in Lawrence, school teacher Diane MacDonald drove up into the parking lot in a car sporting a Scott Brown for Senate bumper sticker in her back window. Stopping her to talk, MacDonald told Oklahoma Watchdog that for over a week she had been blasted with emails from her teachers union telling her and other teachers to be sure and vote for Democrat Martha Coakley. Pointing to her Brown sticker, MacDonald smiled and said, Im really in enemy territory being a school teacher. Noting the pro-Coakley email blasts from her union, MacDonald added: They are using school computers to send out those emails. Thats illegal.
Like I said, nod, wave then vote for Brown.
