THE opening of the presidential library of George Walker Bush at Southern Methodist University gave his supporters an opportunity to remind Americans that the man served his nation well.
What Bush didn't do is what intrigues me most.
To be sure, Bush accomplished much and was, in his words, "misunderestimated."
Keith Hennessey recently gave his graduate students at Stanford's business school some surprising insights into the intellect of Bush, whom Hennessey served as senior White House economic advisor.
"President Bush is extremely smart by any traditional standard," Hennessey said. "He's highly analytical and was incredibly quick to be able to discern the core question he needed to answer.
"It was occasionally a little embarrassing when he would jump ahead of one of his Cabinet secretaries in a policy discussion and the advisor would struggle to catch up.
"He would sometimes force us to accelerate through policy presentations because he so quickly grasped what we were presenting."
Like President Reagan before him, Bush was smart enough to play dumb.
"Mitt Romney's campaign was predicated on 'I am smart enough to fix a broken economy,' while George W. Bush's campaigns stressed his values, character, and principles rather than boasting about his intellect," Hennessey said.
"He never talked about graduating from Yale and Harvard Business School, and he liked to lower expectations by pretending he was just an average guy."
Which Harvard MBA did the people elect president and which did they not?
Presidents should not be measured by the size of their brains, their hearts or even their courage.
That's Wizard of Oz stuff.
A case could be made for Nixon being the smartest, Carter having the biggest heart, and Jackson being the most courageous.
