Can you believe such a crude “know-nothing,” immigrant-bashing, trash-talking, fickle rich guy exploiting working man nativist white prejudices could advance so far politically? He was one of those partying brats with a strict father who turned serious after college, yet still struck many as a candidate “as ridiculous as satire could invent.” But immigration arrivals had quintupled in ten years.

Delighting in secret passwords and elaborate handshakes, members initially dismissed questions about their party—code named Sam—saying “I know nothing.”

Since 1846, more than 100,000 poor Irish Catholics had immigrated to Massachusetts alone. Worcester became 25 percent Irish.  Boston became majority Irish. And Henry Gardner’s promise to “Americanize America” became relevant. ...
