Historian James McPherson points out that the membership in the Know Nothings was “drawn primarily from young men in white-collar and skilled blue-collar occupations. A good many of them were new voters. One analysis showed that men in their twenties were twice as likely to vote Know Nothing as men over thirty.” (1)
Their leaders were also “new men” in politics who reflected the social backgrounds of their constituency. In Pittsburg, more than half of the Know-Nothing leaders were under thirty-five and nearly half were artisans and clerks. Know Nothings elected to the Massachusetts legislature in 1854 consisted mainly of skilled workers, rural clergymen, and clerks in various enterprises. Maryland’s leaders were younger and less affluent than their Democratic counterparts.” (1)
