Here's the hard part. Ask any of the four speech writers what Mr. Obama said in London.
Ask the president himself.
Well, Mr. Lincoln had a way with words. Honest Abe went to Gettysburg and humbly took second billing to the famous orator, Edward Everett, who was the featured speaker on that November 19, 1963. Everett later had the good grace to write the president: "I should like to flatter myself that I came as close to the central meaning of the event in two hours as you did in two minutes."
If Barack Obama had agreed to show up at the Sesquicentennial of the Gettysburg Address, the comparisons might not have been favorable. One of Lincoln's lines might have been quoted: "The world will little note nor long remember what we say here."
And, too, there might have been other embarrassing incidents at Gettysburg. Suppose President Obama were to be greeted by folks who have had their health insurance canceled as a result of ObamaCare. They might have carried signs saying:
Welcome, Honest Barack!
Maybe that's why he's staying home.
