Did They Not Know?

No indication that this was a parody, and the person was in fact an OPPONENT of the president, in this photo caption supplied by the New York Times on its photowire service to client newspapers:

DEBATE SCENE 3
(NYT7) TEMPE, Ariz. -- Oct. 13, 2004 -- DEBATE-SCENE-3 -- Marco Ceglie, a former student of Arizona State University and a member of Billionaires for Bush, gets out of a rented limo holding a sign in support of the Bush-Cheney ticket, near the university in Tempe, Ariz., Wednesday, Oct. 13, 2004. President Bush and Democratic presidential candidate Sen. John Kerry were set for their third and final presidential debate at the university Wednesday night. (Jim Wilson/The New York Times)

The "sign in support of the Bush-Cheney ticket" clearly reads "repeal the first amendment."
