Happy days are not here again, but they are coming for conservatives. Barack Obama — with the lowest approval rating (according to Gallup, 50 percent, four points lower than that of the National Rifle Association) of any re-elected president when inaugurated since the Second World War — has a contradictory agenda certain to stimulate a conservative revival.

Consider his vow to expend political capital on climate change. The absurdity of the Kyoto approach — global climate treaties agreed to by 190 nations — is now obvious even to most former enthusiasts.

Obama can propose cutting U.S. fossil fuel emissions (just 16 percent of the global total) with a carbon tax or cap-and-trade scheme, but Congress will pass neither. So he will be reduced to administrative gestures costly to job growth, and government spending — often crony capitalism — for green energy incommensurate with his rhetoric.
