John, sorry for the late response. We are getting ready to plant peas. Not only Millard Fillmore, but William Seward, Thaddeus Stevens, and Thurlow Weed, the first Karl Rove of the GOP, got their start in the Anti-Masonic party. Many enemies of Andrew Jackson sought the party’s nomination in 1832–John Quincy Adams, John Calhoun, Henry Clay (even though he was a mason). Chief Justice John Marshall, another mason, attended their convention. In the end, they picked William Wirt, yet another mason, who was astonished by the honor, did no campaigning, and carried only Vermont. I wrote about the party in America’s First Dynasty: The Adamses 1735-1918 , and in What Would the Founders Do? Our Questions, Their Answers.
