I forgot to comment on this one earlier. Yes, let's make the US government as parliamentary as we can, without contradicting anything we've already written. I regret making the government look this much like OTL, although some of it was required.
I just reread the post I wrote about the amendments, and I see there's nothing there specifying presidentail elections having every four years. Maybe the president has the power to dissolve Congress and call for an election whenever he or she thinks it's helpful. All the presidential elections we know about so far happened in years that are multiples of four 1800, 1864, 1948, 1968, 2000, 2004, and 2008. Either that's just chance, or there's also a law in place ensuring that election will happen in the next year that's also a multiple of four.
We know the CSA had a variety of Whiggish parties that eventually coalesced into the Conservative Party, and that Alf Taylor was a Whig wannabe. I can see the Whig brand being helpful in uniting northern and southern political parties when Reunification happens. There definitely was a Prohibition Party in the Confederacy, and alcohol was prohibited in the entire south. There was prohibition in some parts of the U.S. in the 1920s, possibly just the south.
The biggest party in the Confederacy were the Democrats and the Conservatives. Many decades later, Nixon was competing against Democrats, who were starting to get Southern Negro votes. I like to think that Nixon's cooperation with Martin Luther King radically changed his party.

Yes! He'd have a cool life story.
