“They were more than hostile. In the first place, I was a south Georgian and I was looked upon as a fiscal conservative, and the Atlanta newspapers quite erroneously, because they didn’t know anything about me or my background here in Plains, decided that I was also a racial conservative.”
—Jimmy Carter (James Earl Carter, Jr.)
“The seagull’s wings shall dip and pivot him,
Shedding white rings of tumult, building high
Over the chained bay waters Liberty—
Then, with inviolate curve, forsake our eyes”
—Hart Crane (1899–1932)
