Cindi Sheehan and friends are holding an antiwar fast. Except most partipants sound like they won’t be sacrificing too much :

Even then, the fiercely partisan debate unleashed may have harmed Sheehan, who faced fierce fire from conservative groups and radio talk show hosts, as much as it hurt the Bush administration’s image over Iraq.
The hunger strike will see at least four activists, Sheehan, veteran comedian and peace campaigner Dick Gregory, former army colonel Ann Wright and environmental campaigner Diane Wilson launch serious, long-term fasts.
“I don’t know how long I can fast, but I am making this open-ended,” said Wilson.
Other supporters, including Penn, Sarandon, novelist Alice Walker and actor Danny Glover will join a ‘rolling” fast, a relay in which 2,700 activists pledge to refuse food for at least 24 hours, and then hand over to a comrade.
