Does Uncommonly Flexible = Flip-Flopping?

Yet, while being a model of consistency, Lincoln was also uncommonly flexible.  He was a leader who would not and did not limit himself.  “My policy is to have no policy,” he’d say.  “I shall not surrender this game leaving any available card unplayed.”  Lincoln would always leave “an opportunity for a change of mind.”
