2020The Democrat wins a large victory, winning the EC easily and the popular vote by about 6 points. The Midwest swings away from the Republicans for one last time, and the Sunbelt trends more Democratic.
2024The reasonably popular Democratic incumbent wins re-election by a narrower margin. Georgia flips, however the Midwest does too. New Hampshire is the closest state.
2028Republicans continue to make inroads in the Midwest, and their candidate manages to flip Florida and Georgia, handing them their first win since 2016. The Democrats, however, continue to make progress in Texas and crack 50% in Arizona and Nevada, a notable feat. The popular vote goes to the GOP for only the second time in the century. This is the final election of the 6th Party System.
2032A climate disaster and the resulting refugee crisis cause a Democratic landslide, as their candidate carries every single coastal state save Alabama. However, the Midwest and Plains stay Republican, a trend in the early days of the 7th Party System. The Democrats win the popular vote 55-44.
2036 Refugees turn West Virginia and Montana Democratic, and play an integral role in keeping Illinois Democratic. However, a 'return to normalcy' means the Republicans gain some ground, especially in the interior where the climate disaster didn't register as much. The incumbent wins re-election easily, however.
2040Hints of a realignment begin to show as the coastal regions begin to shift back towards the Republicans due to urban areas being flooded and their liberal residents moving inland. Resultantly inland states begin to shift towards the Democrats, with the exception of the Southwest, where the emergency response to a drought was botched up by the Democratic president. The vice president wins election, narrowly winning the popular vote.
For extras...
2044Republicans finally win in 2044, due to discontent following 12 years of Democratic rule. The coast swings Republican, though states with inland urban centers (Georgia, North Carolina, New York) stay Democratic.
