Jonathan Schwarz offers a very cynical contrast in Barack Obama Is Powerless Before the Majesty of the Law, contrasting (1) Obama’s acceptance of the (IMHO correct) advice of (all of?) his lawyers that he should not rely on an interpretation of the 14th Amendment that would have allowed him to raise the debt ceiling unilaterally with (2) Obama’s rejection of the (IMHO correct) advice of (most of) his lawyers that he lacked the authority to bomb Libya unilaterally.
Schwartz’s conclusion: “Of course, as people with a sophisticated understanding of the law know, there’s a huge difference between ignoring the debt ceiling and bombing Libya. For instance: Obama wants to bomb Libya.”
To be fair, the consensus on the 14th Amendment issue is probably wider than on the War Powers issue, but even so.
