Neither of these are supposed to be completely plausible, by the way.
Option 1:
Sun Belt StrategyThe Democrats take advantage of rising minority populations and go for Texas, Georgia, Florida, Arizona, and the Carolinas, managing to win all those areas, but in the process largely abandon the midwest and parts of the northeast to the Republicans. Illinois and Rhode Island become tossups. The Democrats take a liberal position on social issues and a centrist one on economics, echoing Bill Clinton's presidency.
Option 2:
White Working Class StrategyThe Democrats focus their efforts on winning back the midwest, and it is successful, making Missouri, Montana, and Indiana tossups once again, and bringing Michigan, Wisconsin, Iowa, Ohio, and Pennsylvania to Lean D. However, the south becomes even more Republican and Virginia and Florida revert to Lean R. Kentucky and West Virginia move to Lean R. Alaska also comes into play. The Democrats become socially moderate and focus less efforts on guns and immigration, but take further-left positions on economics than currently.
