The name of several comic book characters published by DC Comics. The original Green Lantern, Alan Scott was created by Martin Nodell and first appeared in "All American Comics" #16 in 1940. In 1959 the concept of the Green Lantern was reimagined with the character of Hal Jordan who debuted in "Showcase" #22. Several human Green Lanterns including John Stewart, Guy Gardner, and Kyle Rayner have followed the tradition of Hal Jordan as well as thousands of alien Green Lanterns across the universe.

The Green Lanterns all share the basic concept of possessing a Power Ring which can create virtually anything the wearer wishes, limited only by the wearer's willpower and imagination. The Power Ring carries a finite charge and must periodically be recharged from a Power Battery in the form of a green lantern.

A belief that political miracles are achieved by sheer will force. Proponents of the Green Lantern Theory have attributed failure and compromise to a lack of presidential willpower. Matthew Yglesias came up with the Green Lantern Theory of Geopolitics* to ridicule conservatives who claimed "the only thing limiting us is a lack of willpower" in foreign policy. The Green Lantern Theory was later applied to the Obama Administration who seemed to lack the will power to make the radical changes in policy such as universal health care, lowering medical costs, banking reform, and peaceful negotiations that people had hoped for., especially after the Republicans took over the US House in 2011.
Bernie supporters are big proponents of Green Lanternism and fail to recognize this kind of “Presidentmania” where the President can get anything done if he really wanted to, fails to take into account the significant amount of bureaucracy legal barriers, and the number players the president has to deal with such as legislators, special interests and Jurists who often do everything in their power to block the president from making these achievements.
