Proabably driven by liberal tolerance of social pathologies in the "blue" parts of those "red" states - like New Orleans, Atlanta, Miami, and Dallas.
Red states are more likely to be in the South where there are large numbers of poor blacks and whites who are more likely than wealthy white liberals to exhibit outwardly pathological behavior.
Thats not to say these well to do libs are virtuous or "better" but they can afford to hire therapists and "life coaches"for their wayward offspring much easier than someone in the Miss.Delta or hills of Arkansas.
