A few general thoughts I've been having about TL-191 US Politics, mainly posted to provoke further discussion
I'd like to put forwards the case that the Butler faction of the Republicans, rather than just entering the Democrats to influence their policy after the Second Mexican War, rather almost completely took over the Democratic Party, resulting in just about the most successful program of entryism in TL-191's history. There are a few reasons I believe this to be the case; Every canonical Democratic President and Presidential candidate after the Second Mexican War that we know of was an otl Republican, and just about the only otl Dem with any significance within the party is Truman. Most other otl Democrats are Socialists.
To understand why this is we have to get into the function of the Republican Party after the Civil War in otl. In the 72 years between 1860 and 1932, the Democrats won exactly four Presidential elections. That makes for 16 of 72 years under Democratic Presidents, not including Andrew Johnson. The Republicans truly became a natural governing party, and as such became the party of all of the post-civil war "in" groups, most importantly the northern bourgeois industrialists and businessmen. The Democrats meanwhile became a broad tent of everyone left out of the post-civil war order, namely, southern whites, anti-corruption crusaders, and immigrants. The Confederate victory in the War of Secession doesn't really change the balance of power in this regard; the north will still industrialise, and the otl supporters of the Republicans will still want a government that conforms to their interest, in a sense abiding by the Hamiltonian lineage of the Republicans, rather than the primary Jeffersonian or Jacksonian agrarian-populist lineage of the Democrats.
As the Republicans flounder therefore, these industrialists who constitute the US' ruling class have to find a new vessel for their preferred form of government; continued government by the Democrats in their current form is not desirable, so they can either form a new Hamiltonian party, or try to appropriate the Democrats. Butler dictates their course through his decision to cross the floor, and the "party switch" of sorts comes about by the turn of the century, with the (canonical) Presidency of Thomas Reed, otl Czar of the late-third party system Republicans, and with the (non-canonical) defection of William Jennings Bryan to be the Republican Party's Presidential Candidate, bringing with him the agrarian populism of the Democratic tradition. The Democrats therefore take the Hamiltonian lineage, and become the preferred party of the industrialists, therefore being a tarriff party, unlike otl. The Republicans, meanwhile, become more agrarian, populist, Jeffersonian, and similar to the free trader Democrats of otl. One area where the parties have not necessarily switched is the issue of parliamentary (congressional) or presidential government. The Democrats will still probably favour a strong executive, while the Republicans are more congressionally minded. The Whigs in the CSA also derive from the Hamiltonian tradition more than the Jeffersonian one[1].
The Socialists, meanwhile, like the Labour Party in the UK, is largely distinct from the previous Hamiltonian and Jeffersonian (Whig and Tory[2]) traditions that previously found themselves in each of the major parties in their country. Through Lincoln there is some link to the Hamiltonian side (Lincoln was originally a Whig after all), but the fact is the Socialists are very much a new development in this regard. They likely conform to their international comrades' preference for parliamentary, rather than executive rule however. Like the Labour Party of the '20s and '30s, issues of free trade and protectionism will likely complicate relations between farmers and industrial workers in the party.
The Socialists probably transform US politics even further through their being a mass party. Party dues were (and still are!) foreign to the Democrats and Republicans of otl, but the Socialists will probably force at least the Democrats to change in that regard. What results is a party system much more familiar to foreign observers; unlike otl, where until recently the major parties have been coalitions of often disparate regional and ethnic interests, the Democrat-Socialist duopoly is ideologically charged, with smaller but more committed party membership.
The high point of Republican electoral fortunes after the Second Mexican War prior to 1944 I see as likely being 1892, with a more western focused candidate (John Sherman?), while the pre-Great War Socialist high I would expect to be a Robert La Follette run in 1908. The Republicans in my mind first fail to win any states in 1900, then in 1908, then in 1916, and then from every election between and including 1924 and 1932.
From 1920, its pretty clear that a new party system distinct from the Democratic dominance of 1884-1920 has emerged. I see Pennsylvania, California, Ohio, Illinois, and New York as the largest swing states of that election. By 1928, the Socialists are probably better positioned in New York, Illinois, Pennsylvania, and Ohio, though the latter two are still more competitive, while competition moves more towards the plains as the Socialists cannibalise the Republican vote. By 1936, lower New England may well be the nation's swingy-est region, a breakthrough that I think is best positioned to continue to shift that formerly solid blue region red. Smith's Catholicism meanwhile probably hurts in the plains Blackford called home. My version of the 1940 election sees a a few trends continue/start up; Smith does worse than Sinclair or Blackford in '28, yet he still wins a New England state in Rhode Island, reflecting strengthening Socialist fortunes in the region. Meanwhile Taft does better in the lower-north, which I expect to be a defining factor in the post 1944 elections. The Mormon vote likely goes hard for Smith, giving him states like Wyoming, Nevada, and Idaho, which he previously lost in '36. It is these gains which are most preserved by La Follette in defeat in 1944. More broadly the shift from fifth (1920-1944) to sixth (1944-whenever a Socialist landslide changes the game again) party systems probably see the Socialists do better on the West Coast, in New England[3], and in the rockies, while continued anger at the Richmond agreement proves most potent in Ohio and Pennsylvania, and to a lesser extent Indiana, Illinois, and New Jersey.
