Imperial Dusk - yet another alt-history mod for Hearts of Iron 4

So... Has Mustafa Kemal and his ideology been as prominent for the Ottomans as they were in OTL? Or has he fallen on the wayside in favor of the extremist (likely Vitalist) figures like Nihal Atsiz and his less extreme protégé Alparslan Turkes?

Mustafa Kemal has been Prime Minister of the Ottoman Empire since 1918. His ideology is somewhat different ITTL, with Ottoman nationalism replacing Turkish nationalism (his view is that promoting Turkish nationalism helped inspire the Arab Revolt), and of course no republicanism. Other reforms have gone through, especially industrialization, social, and political reforms. The Ottoman Empire is still officially a Muslim nation, but the clergy are limited to controlling family law (similar to modern Israel IOTL, if Israel cared more about its non-Jewish minorities). Outside of the Sultan, which fills the role of the executive, the government is democratic, with a degree of federalism most comparable to modern Germany. Each province (vilayet) has an elected governor, and sends representatives to the General Assembly in Constantinople. There have been some efforts of late to incorporate Turkish nationalism into Ottomanism without angering the minorities by suggesting ethno-historical links between the Turks and other peoples of the Empire (the major groups are the Armenians, Kurds, Turks, Syrian Arabs, and Jews). The Ottomans are actually the poster child for reformed monarchy. It is significant that Kemal's Five Arrows Party (the arrow representing republicanism was dropped) has successfully incorporated mainstream Jewish, Armenian, and Kurdish political parties into its ranks. The Five Arrows Party fills both the progressive and liberal roles (it has two wings).

However, there are storm clouds on the horizon. Kemal himself is in failing health. His reforms have angered conservatives, and there is a powerful conservative party - the Five Pillars Party - that could take power if he dies, which has a good chance of both pissing off the non-Sunni minorities and giving the weakened socialist movement some real fire. To make matters worse, the Arabian Caliphate has not only claimed the title of Caliph, but has been casting hungry glances at the Empire for many years.

Nihal Atsiz is the leader of the Turanist party in Turkey, filling the centralist role (although it has a futurist wing). His party can come to power, although not easily - the primary opposition is the Five Pillars Party. Alparslan Turkes is only 19, and is focused on his plans for a military career. He will not appear in the mod.
I've decided on a slight revision of the timeline regarding the lead-up to the American Revolution. Here is the new series of events (apologies for the slain butterflies, given that this timeline has an 1861 POD):

October 1901: President William McKinley survives the assassination attempt which killed him IOTL. However, he is traumatized by the experience, and begins a gradual decline into paranoia (although this is not widely known).

July 1902: President McKinley sends in federal troops to end the 1902 Coal Strike. Several miners are killed, and no concessions are made. This produces public outrage, and opens a rift between McKinley and Vice President Theodore Roosevelt.

November 1902: Having built on the public outrage from the coal strike, the Socialist Party surges in the mid-term elections, winning a slim majority in the House of Representatives. Daniel DeLeon (S-NY) is voted in as Speaker of the House. The Senate is still under Republican control, although a few Socialist senators are elected, with Senator Eugene V. Debs (S-IL) becoming the socialist Senate minority leader.

July 1904: President McKinley decides to seek a third term in office. He grudgingly agrees to keep Roosevelt on the ticket, but there are rumors that McKinley no longer trusts his VP. William Jennings Bryan wins the Democratic nomination, and Eugene Debs is nominated by the Socialists.

November 1904: Senator Eugene Debs wins a plurality of the popular vote (due in no small part to McKinley's increasingly irrational rhetoric), but not a majority of the Electoral College. With a Socialist House and a Republican Senate, it is assumed that Debs will become President with Theodore Roosevelt as Vice President. Having been effectively isolated within the McKinley administration, Roosevelt leaves Washington for New York, hoping to start working with his new President.

December 1904: After a combination of bribery, persuasion, and coercion, enough electors turn faithless to reelect McKinley to a third term. Both the Socialists and Democrats (and many Republicans) are outraged. Debs calls for a weeklong general strike. In response, McKinley declares the Socialist Party to be in a state of rebellion, and summarily strips them of their citizenship (invoking the 1866 law used to strip Confederate veterans of their citizenship). The American Revolution (sometimes called the Second American Civil War) begins.
