bicycles and mass transit

Study after study after study after study shows exhaust from gas cars and diesel engines to be a major factor of disease in our world, and — tragically — in our children. With such a large amount of information on air pollution out there, why on earth would an administration claiming to care for children cut funding for clean transport (not to mention the EPA)? Is the party and its president simply disrobing its pro-child guise, its pro-life guise with the understanding that voters won’t pay attention or care?
