What happened to many Anti-Masonic politicians in the late 1830s?

In the late 1830s, many politicians associated with the Anti-Masonic Movement saw their political influence wane as the movement declined. Much of the reformist energy that fueled Anti-Masonry was absorbed by the growing antislavery agitation. Consequently, most Anti-Masonic politicians joined the newly formed Whig Party. The Anti-Masonic Party, which was the first American third party, had achieved some success in state and local elections after its formation in 1826, largely in response to the mysterious disappearance of William Morgan, who was believed to have been murdered by Masons. However, the party's national influence peaked with its presidential candidate William Wirt in 1832, and it began to decline thereafter.12
