Or, an example of history repeating, er, threats
Though, in fairness to Mr. Jackson, I think this one was much more sincerely offered:
Unfortunately, for the Captain and his Guard the animosity ran deeper than a few office seekers. Both Cushing and Tyler received “hate mail” from around the country. Vituperative James Campbell of Philadelphia urged Cushing to intercede and persuade Tyler, “a miserable, paltry, third rate county court scoundrel,” to resign. Campbell, somewhat more irrational than most of Cushing’s correspondents, suggested that for his treason to his party Tyler should “have his privates cut off and while yet still alive to have them nailed to a cross as a warning to political traitors hereafter.” In case any doubt existed he attached a graphic color rendering of his intent.
