There have been many poets writing about presidents, but only a few who have read poetry at POTUS inaugurations.
Here's a poem by Walt Whitman "Specimen Days [The Inauguration]"
March 4th.—The President very quietly rode down to the Capitol in his own carriage, by himself, on a sharp trot, about noon, either because he wish'd to be on hand to sign bills, or to get rid of marching in line with the absurd procession, the muslin temple of liberty and pasteboard monitor. I saw him on his return, at three o'clock, after the performance was over. He was in his plain two-horse barouche, and look'd very much worn and tired; the lines, indeed, of vast responsibilities, intricate questions, and demands of life and death, cut deeper than ever upon his dark brown face; yet all the old goodness, tenderness, sadness, and canny shrewdness, underneath the furrows. (I never see that man without feeling that he is one to become personally attach'd to, for his combination of purest, heartiest tenderness, and native Western form of manliness.) By his side sat his little boy, of ten years. There were no soldiers, only a lot of civilians on horseback, with huge yellow scarfs over their shoulders, riding around the carriage. (At the inauguration four years ago, he rode down and back again surrounded by a dense mass of arm'd cavalrymen eight deep, with drawn sabres; and there were sharpshooters station'd at every corner on the route.) I ought to make mention of the closing levee of Saturday night last. Never before was such a compact jam in front of the White House—all the grounds fill'd, and away out to the spacious sidewalks. I was there, as I took a notion to go—was in the rush inside with the crowd—surged along the passage-ways, the blue and other rooms, and through the great east room. Crowds of country people, some very funny. Fine music from the Marine Band, off in a side place. I saw Mr. Lincoln, drest all in black, with white kid gloves and a claw-hammer coat, receiving, as in duty bound, shaking hands, looking very disconsolate, and as if he would give anything to be somewhere else.
Here is an article about how J.F.Kennedy invited Robert Frost to read at his inauguration. There is an audio clip at the end of Frost, in his old voice, reading "The Gift Outright." Robert Frost was the first poet to read in the program of a presidential inauguration in 1961.
The Gift Outright
The land was ours before we were the land’s.
She was our land more than a hundred years
Before we were her people. She was ours
In Massachusetts, in Virginia,
But we were England’s, still colonials,
Possessing what we still were unpossessed by,
Possessed by what we now no more possessed.
Something we were withholding made us weak
Until we found out that it was ourselves
We were withholding from our land of living,
And forthwith found salvation in surrender.
Such as we were we gave ourselves outright
(The deed of gift was many deeds of war)
To the land vaguely realizing westward,
But still unstoried, artless, unenhanced,
Such as she was, such as she would become.
Elizabeth Alexander read "Praise Song for the Day" at President Obama's first inauguration. The poem is long, slender and passionate, like the man it honors.The link to the Poets.org site also has a video recording of her reading it. My favoirte parts of this poem are when Alexander describes the people of America --
Someone is stitching up a hem, darning
a hole in a uniform, patching a tire,
repairing the things in need of repair.
Before Obama, Bill Clinton had resumed the practice of having poets at the inauguration, with Maya Angelou, who's poem "On the Pulse of Morning"can be read in its entirety here. Angelou speaks for trees and rocks and rivers, as well as for peoples from all over the world who have found their way to America. At his second inauguration, Clinton asked Arkansas poet Miller Williams to read, and his poem "Of History And Hope" can be read here. In his very first line, "We have memorized America," he associates America with poems children have been asked to learn by heart for centuries.
I found a ready-made Inaugural Poem lesson plan at TeacherVision.com. While these poems are often critically panned, the general public tends to love them. And that's what a good poet does, write and speak to her audience. Children will respond to the familiar language and enjoy the simpler imagery.
I'm going to save my comments on "One Today" by Richard Blanco until tomorrow. But you can hear him read it here, if you like. I find the stream of tweets below his face distracting, but the recording is very good. If you can, listen to the poem first, don't read along. It's better that way, that's the way it was intended to be given, to be heard.
