[See NewsBusters for more.] Tuesday night saw something rare on PBS, a conservative voice. Senator Ted Cruz appeared on liberal Tavis Smiley's program and hit back at the host's pro-Democrat questions. Smiley demanded, "Well, why can't we raise the minimum wage to a living wage? Why won't you fight for that?" Cruz quickly retorted, "The people who will hurt the most... How does it impact the most vulnerable? Every time you raise the minimum wage, the people who will hurt the most is the most vulnerable."
