Looks like Obama wants to get re-elected now, plain and simple. I don't think that's happening, however. You've done far too much damage to the country with your liberal, elitist, Marx-loving social experimentation. That ivory tower academic shit doesn't work in real life.
Furthermore, how can he "overrule" an organization that was just acting on his direction in the first place? It's obvious the EPA was being used to shield him from criticism over the stupid global warming moves he was throwing onto our economy.
WASHINGTON (AP) — President Barack Obama on Friday scrapped his administration's controversial plans to tighten smog rules, bowing to the demands of congressional Republicans and some business leaders.
Obama overruled the Environmental Protection Agency — and the unanimous opinion of its independent panel of scientific advisers — and directed administrator Lisa Jackson to withdraw the proposed regulation to reduce concentrations of ground-level ozone, smog's main ingredient. The decision rests in part on reducing regulatory burdens and uncertainty for businesses at a time of rampant uncertainty about an unsteady economy.
