This is a bit old, but The New York Times had a recent piece on Obama’s “pragmatism.”
Here are some of the references:
In some of his earliest skirmishes, Mr. Obama eventually chose pragmatism over fisticuffs.
….And Thursday, Mr. Obama suggested that he would not fight in Congress to renew an assault weapons ban that expired in 2004. It was the latest example of the pragmatic approach he adopted after winning the presidency by promising to challenge entrenched interests and put the public good ahead of political expedience.
….Pragmatism, they add, is an Obama hallmark, and among the changes he promised — and has delivered — is a break from his predecessor’s often uncompromising style.
