Maps from a TL where the United States absorbs Mexico in 1848. The present day is 1930.
Political/Administrative: This map shows the states of the USA and its satellites in Central and South America. Note that most of the Mexican states were left in their 1848 borders, but the US administration created the Territory of Mexico from south-central Mexico and absorbed the secessionist Republic of Yucatan. Also note that the southern Californian state, Colorado, was created before Baja California was formed as a state from the Sonora Territory. Baja California and Colorado have never been united.
Ideological: The primary political parties in the United States are the Republicans (liberal, represented in yellow), Democrats (conservative, represented in blue), and Socialists (socialist, represented in darker red).
The Socialists are most popular in the Steel Belt (midwest), and the Brass Belt (Pacific Mexico). They tend toward a more syndical model of socialism, favor protectionist trade policies, prefer workplace democracy to economic planning, oppose military interventionism, and advocate for extensive separation of church and state. The Socialists are the third strongest political party in the US.
The Republicans are most popular in the Great Plains, Northeast, and the Valley of Mexico. They favor free trade, deregulation of the economy, subsidies for businesses, and religious pluralism. They tend to be in favor of expanding the military and support some military interventions, but are not actively expansionist. They are popular in the Great Plains and Northeast for their emphasis on agrarian issues and small-town life, and their pandering to the German-American vote. They are also well liked in Texas due to their support for the oil industry.
The Democrats are most popular in the Gulf Southeast and the Pacific Southwest regions. They are associated with old hierarchies, and enjoy the support of the Mexican cavalier class in the Pacific Southwest and the southeastern planter class. The Democrats support a protectionist trade policy, promote economic regulations, view faith as an important part of both public and private life regardless of whether one is Catholic or Protestant, and support the expansion of the United States in the Caribbean, Pacific, or into Quebec.
The other two parties in the United States are the Radicals, who are anarcho-communist and are mainly supported by the natives in southern Mexico, and the Cristeros, who are Catholic supremacists and seek to separate Mexico from the United States as a theocratic republic.
Outside of the United States, most of its client states are right-wing liberal (gold), nationalist and state-capitalist (orange), or reactionary nationalist (dark blue).
Brightest green (New Hampshire, New Jersey, Delaware, California) indicates the most free states, with regular and contested elections, a culture of free speech and free assembly, and universal suffrage for men and women.
Yellower green indicates mostly free states, with regular and contested elections, but without women's suffrage or with widespread voter suppression against minorities.
Yellow indicates flawed democracies. These states lack a democratic culture due to the legacy of slavery, strict class hierarchies, religious influences, or gerrymandering and machine politics rendering the actual votes irrelevant.
Lighter orange indicates hybrid regimes, with power sharing between the state and undemocratic entities such as the Radicals and Cristeros or the Oklahoma Mafia. This also indicates territories, due to their lack of political representation.
Orange indicates authoritarian regimes, like the US puppet states in El Salvador, Guatemala, Honduras, and Venezuela, or the communist filibusters in Belize.
Red indicates totalitarian regimes. The Empire of Haiti is the only example depicted, and is like a cross between nineteenth century Paraguay and the Reign of Terror in France, all presided over by the House of Soulouque.
