During the campaign, Obama was an object lesson in equanimity.
Insinuate he's Muslim or sympathizes with terrorists, and he brushes
off the mud. Hammer him with trumped up charges -- "sexist,"
"socialist," un-American" -- and he rolls with the punches. He simply
doesn't let it in. He demonstrates that we have the ability to master
whether we allow setbacks and attacks to throw us off course.

A lot has been written about Obama's calm in the face of adversity
over the course of the last 21 months. Less noted has been how he
displays that same centeredness in the face of triumph.
