Does Mr. Obama Understand?

Does Mr. Obama understand that an actual default on our federal government debt would almost unarguably be an impeachable offense?

Payments on the government's debt are protected obligations, prescribed by the 14th Amendment to the Constitution.

The validity of the public debt of the United States, authorized by law, including debts incurred for payment of pensions and bounties for services in suppressing insurrection or rebellion, shall not be questioned. 

This has been and is currently understood to mean that the public debt has a priority over all other obligations of the government. If Mr. Obama, or his representatives in the executive branch, the branch of the government responsible with mundane tasks like issuing checks, actually paid anyone or anything prior to currently required debt payments, he would and should be impeached for a serious breach of his explicit constitutional duties.
