Where Obama's Green Lantern lies

Sean Trende offers up a kind of excuse for pundits and centrists who indulge in what political scientist Brendan Nyhan calls Green Lanternism. --lambasting Obama for failures of ill-defined "leadership," i.e., for failing to charm the Republicans out of their scorched-earth opposition or to overcome the extreme constraints the Constitution imposes on presidential power in domestic affairs.   According to Trende, the expectation that Obama would exert magical powers to overcome opposition derives from the campaign Obama ran in 2008:

Many of the president’s supporters thought they were voting for the Green Lantern in 2008.

Remember, the actual policy differences between Obama, Hillary Clinton, and John Edwards were pretty limited. To help distinguish himself from the pack, and to attack Clinton indirectly, Obama all but dressed up in green tights, claiming that his candidacy would enable us to put old arguments behind us, bring people together, and transform the country.

There is an element of truth to this, as there was an element of malarkey in Obama's promise to usher in "a different kind of politics."  But only an element, on both sides of that equation. Obama's core pitch and promise in 2008 was more realistic and tough-minded than "I can melt the opposition."
