This fun book, by Brenda Wineapple, has the subtitle The Trial of Andrew Johnson and the Dream of a Just Nation. Excerpt:
“The long haired men and cadaverous females of New England think you are horrid,” Johnson’s secretary reported to him. “I had a conversation with an antique female last night, in the course of which she declared that she hoped you would be impeached. Said I ‘Why should he be impeached — what has he done that he should be impeached?’ ‘ Well,’ replied she, ‘he hasn’t done anything yet, but I hope to God he will.'”
