candy crowley, ron brownstein thanks for your perspective. up next cnn is on the front lines of serious civil war with pro government fighters openly angry at the u.s. and senator john mccain joins us to vent his strong differences with the president over syria. that's coming up. i am an american success story. i'm a teacher. i'm a firefighter. i'm a carpenter. i'm an accountant. a mechanical engineer. and i shop at walmart. truth is, over sixty percent of america shops at walmart every month. i find what i need, at a great price. and the money i save goes to important things. braces for my daughter. a little something for my son's college fund. when people look at me, i hope they see someone building a better life. vo: living better: that's the real walmart.
