It's been almost a year and a half (!) since I posted the 1912 House map, but at the time I also made one of 1914, and I've now made a 1916 one as well, so it feels like I should post them.
Woodrow Wilson took office in March 1913, with a Democratic supermajority to back up his policies, and set about implementing them. Notably, for the first time in US history, he set out a coherent domestic policy agenda ahead of time, and after his inauguration held a line speech to Congress, the first time in over a century that any President had addressed the legislature. This had been widely regarded as a threat to the separation of powers, but Wilson made it into a tradition, and the modern practice of delivering an annual State of the Union speech began here (although there hasn't been one every year since 1913). In general, Wilson took a very practical view of political traditions - he was the first and so far only political scientist to serve as President, and in his time as an academic he'd even argued in favour of a parliamentary system, which he believed would make governance more efficient and solidify the already-dominant position of Congress in domestic affairs.
Wilson's domestic policy consisted of three major pillars, each of which changed the political landscape of the US in its own way. The Revenue Act of 1913, better known as the Underwood Tariff Act, slashed tariffs and compensated the lost revenue by instituting the first federal income tax - initially with a top marginal rate of 7%, although this would quickly rise for reasons we'll get to in a bit. The Federal Reserve Act established the Federal Reserve system, giving the US a central bank of sorts for the first time in decades, although it was and is organised very differently from most other central banks. Finally, the Clayton Antitrust Act expanded the pre-existing Sherman Antitrust Act and was accompanied by the Federal Trade Commission Act, which created the first federal agency dedicated to enforcing antitrust laws.
In foreign affairs, Wilson was less successful. He appointed William Jennings Bryan to the State Department, and the two attempted to chart a less imperialist course than the previous Republican administrations, but not a whole lot came of this in practice. The European powers were uninterested in Bryan's appeals to Christian pacifism, and during Wilson's first years the US launched several armed interventions in Latin America - most infamously the occupation of Haiti, which would last almost twenty years, and the seizure of the port of Veracruz following the overthrow of President Francisco Madero and the ensuing civil war in Mexico. In spite of Bryan's protestations, the First World War broke out in July 1914, and Wilson's only major foreign policy achievement thus far was keeping the US neutral. This would become harder and harder to do, but as of the 1914 congressional elections, there was not much impetus for the US to involve itself in European affairs, and the war was not a major part of the election campaign.
Aside from Maine, which continued to hold its elections in September, all 48 states now held their congressional elections on November 3, 1914. This was the first time members of both houses of Congress were up for direct election, the 17th Amendment having been passed just after Wilson's inauguration in 1913. I contemplated putting the Senate on the map as an inset, but decided against it because a) the US is too square to make something like that work, and b) Senate elections are too square for me to want to map them. There wasn't anything like the same sort of change to House elections, though a number of states that hadn't redistricted in 1912 despite gaining seats did so now. Illinois, Pennsylvania, Texas, Alabama and West Virginia still held at-large elections by this point, and Montana and Idaho continued to elect their two-man delegations statewide as well.
While a few incumbent congressmen stood for re-election as Progressives, there was really not much of a Progressive Party by this time, and most of the local politicians and activists who had supported Roosevelt's run in 1912 were now back in the Republican fold. In other words, there was a united opposition, and much of the gains made by the Democrats in 1912 were clawed back by the GOP in 1914. The Democrats kept their majority, but lost sixty-one seats. Six of the ten Progressives elected in 1912 kept their seats, while the Socialists, despite losing nearly half their votes, succeeded in getting a member elected where they'd failed in 1912. Meyer London would now represent the Lower East Side of New York, while the tiny Prohibition Party got Charles Hiram Randall elected as a fusion candidate in Los Angeles, displacing incumbent Progressive congressman Charles W. Bell by a narrow margin. Independent "small-p" progressive William Kent also won re-election in his Northern California district.
Wilson's policies did not change substantially following the 1914 midterms, but that may have done him more harm than good, as the war in Europe became more and more dominant on the agenda. Cultural ties to the UK combined with the democratic nature of it and France as well as the highly publicised brutality of the advancing German armies meant that public opinion in the US favoured the Entente side of the war, and a large popular movement arose during 1915 calling for the US to strengthen its armed forces and cultivate a willingness to defend the country. On the other hand, a lot of people had come to the US during previous years to avoid the militarism of their European homelands, and to them the idea of "preparedness" was completely anathema. This was particularly true of the German community, which was strong in the Midwest in particular, and strongly opposed the idea of going to war with their cousins in Europe regardless of what they might think of the Kaiser. The Midwest included several key swing states, then as now, and one of the strongest Democratic constituencies there were German Catholics, so Wilson found himself in an awkward position. It was only made more awkward when Germany announced its policy of unrestricted submarine warfare, which made merchant vessels military targets and led to a number of high-profile US casualties - most famously the sinking of the RMS Lusitania in May 1915, which killed over a thousand people including 128 US citizens.
The reunified Republican Party were convinced they could use this to throw Wilson out of office - after all, hadn't they won every presidential election between 1896 and 1908 by wide margins? There was the issue of the ideological divide between progressives and conservatives, which was still there even if the party was back together, but they solved this by nominating a compromise candidate in the form of Supreme Court justice and former New York governor Charles Evans Hughes. Hughes was known as an anti-corruption crusader and had voted to uphold most social and economic regulations, but his personal views weren't necessarily all that progressive (for instance, he was known to oppose the federal income tax). On the issue of the war, Hughes stopped short of calling for the US to join the war (unlike Theodore Roosevelt, who was fully in the interventionist camp), but supported the Preparedness Movement and attacked Wilson for not doing enough to defend American interests.
Hughes went into the election as the clear favourite, because, as mentioned, the Republicans were regarded as the natural party of government at this time. The Democrats ran a strong campaign, though, and they had a popular economic agenda to campaign on. In addition to the Solid South, Wilson swept most of the West, including taking California by a margin of just under four thousand votes. Aside from Ohio, most of the Midwest and the East went for Hughes, but this did not turn out to be enough - by a 277-254 margin, Wilson won a second term in office.
The accompanying congressional races were no less dramatic. Once again, the Democrats sustained losses, though they weren't as dramatic as those in 1914, and these were primarily concentrated in the Midwest. The exception was Ohio, which saw four seats flip to the Democrats - I have no idea why, but it is worth noting that Wilson also did much better there than in any of the neighbouring states. The nationwide result was even closer than that of the presidential race, returning a House with no overall majority for the first time since the 1850s. In fact, if we look at official Republican candidates only, they and the Democrats were perfectly tied at 214 seats each, though this is slightly misleading given that two candidates elected as independents were members of the Republican Party and sat with them in Congress. With this in mind, you'd expect the Republicans to be able to take control of the House, but not so. The Democrats were able to come to an agreement with Meyer London and the three remaining Progressives, giving them a razor-thin majority in the House that was able to re-elect Champ Clark as Speaker.
A couple of other notes - Alabama and West Virginia redistricted for this election, leaving only Illinois, Texas and Pennsylvania with at-large seats, and Idaho and Montana electing their delegations statewide. The latter would make history during this election, as one of the incumbent Democratic congressmen retired and was replaced by Republican Jeannette Rankin, the first woman ever elected to Congress and the only woman ever elected to Congress from Montana. At this point in time, only a few states even let women vote in federal elections, though that would soon change. Rankin was also notable as one of the most committed pacifists in Congress at this time, voting against the declaration of war in 1917 as well as that against Japan in 1941 (the latter as the sole dissenting vote).
