The origins of the Republican party
The Republican party pledged to fight the “twin relics of barbarism”: slavery and polygamy
Ironic that Mormons now overwhelmingly vote Republican
What beef did they have with polygamy?
Jeebus
Generally speaking it's also not wise to have polygamy (as opposed to polyamory) in cultures without a lot of young males dying. Tends to lead to a bunch of horny and angry incels.
The Mormons had it strictly because Mormonism is a cult that was designed for Joseph Smith to get child "brides."
And clowns today will tell you that a third party is doomed to fail because of the scawy two party system and first past the post.
FPTP ultimately results in a two-party system. That doesn't mean it's a two-party system 100% of the time. If a party truly screws up, that party can die and be replaced. You'll still end up with two parties for the vast majority of the elections.
And that's exactly what happened. Reality lines up with the math.
