If a new Washington Post poll is correct, a majority of Republicans now believes the war in Afghanistan is not worth fighting. Fifty-two percent of GOP voters -- long the war's most resolute supporters -- have lost faith in the effort, along with 72 percent of Democrats and 66 percent of independents.

Not surprisingly, when Americans don't think a war is worth it, they want to get out -- especially when that war is in its second decade. Recently pollster Scott Rasmussen found that 53 percent of likely voters support an immediate withdrawal of U.S. troops from Afghanistan. That number includes 42 percent of Republicans and strong majorities of everybody else.
