Groups -- While there are partisan differences on a major troop withdrawal this summer, it's supported by majorities across party lines -- 89 percent of Democrats, 72 percent of independents and 59 percent of Republicans. Republicans, meanwhile, are more apt than others to say the war has been worth fighting (albeit just 53 percent) and to say it's contributed to long-term security, 67 percent. Even among Republicans, though, 28 percent say the war, now in its 10th year, has contributed "a great deal" to the long-term security of the United States.
