On ABC’s “This Week” Sunday, conservative columnist George Will made an astute addition to the list of people and circumstances on which President Obama places blame for his own policies and their lackluster results.

Instead of acknowledging his own failure to lead, Will noted yesterday, “This president has blamed George W. Bush, the Japanese tsunami, the euro, Greece, the Arab Spring, the Republicans, the tea party and ultimately James Madison for giving us separation of powers for all his problems.”

Adding Madison to the list is undoubtedly a reference to comments the president has made recently wherein he complains that constitutional restrictions on his authority prevent him from unilaterally enacting his liberal agenda:

Thank God for James Madison, the “father” of our Constitution.
