They are trying to paint Perry as a racist like they tried to link President Bush with the Jasper Texas dragging. It was Governor Perry and the people of the state of Texas who took in thousands of Katrina victims - most of whom were black.
Trial lawyers and teacher unions (#1 and #2 backers of Dems — and NOW) said they would do everything do defeat Perry because of his push against them.
They are also trying to take Cain down with him with these questions.
