Cindy Sheehan and her supporters--about 200 of them--have been demonstrating near the Bush ranch in Texas. The poor turnout is blamed on both the holiday and the bad weather (some rain). Maybe. But note that the article mentions that there were two-and-a-half-times as many people (circa 500) who turned out at the ranch to call on Bush to put pressure on the Ethiopian government to release detained opposition party leaders in that country.
Also note these photos from Sheehans book signing. No bad weather in the tent, I would say.
