Paul Krugman recounts a similar sort of thing during the 2009 Tea Party town-hall invasion:
"There was a telling incident at a town hall held by Representative Gene Green, D-Tex. An activist turned to his fellow attendees and asked if they 'oppose any form of socialized or government-run health care.' Nearly all did. Then Representative Green asked how many of those present were on Medicare. Almost half raised their hands."Paul Krugman, The Town Hall Mob, The New York Times, Aug. 7, 2009, at A19. How do you deal with unwitting hypocrites?
