Political geography without the Great Migration

[True Federalist (진정한 연방 주의자)]

No Great Migration also likely means no Northern Cities racial backlash among working/middle-class whites.

It may also mean no major civil rights bills, at least in the 1960s, since the growing power of non-disenfranchised Northern blacks was a major part of what pushed Northern politicians to back the civil rights movement.

Maybe/maybe not. It depends greatly upon why the Great Migration didn't happen. Is it because the North proves much more hostile to Negroes moving north or is it because Southern Whites force their Negroes to stay or most unlikely of all, is it because conditions for colored people are more advanced than they were in reality?

Another interesting map would be US without 1965 immigration act+ enforcing immigration laws at the southern border.

Without the 1965 Immigration Act almost all those Latin Americans wanting to immigrate here could.

Before the act, quotas capped immigration from countries corresponding to their percent of the US population.  Latinos were under 5% so Latino immigration couldn't exceed that by more than 3%, per the quota law.  3rd world immigration was capped to maintain the demographics.

The quotas before 1965 didn't apply to countries in the Americas. Now there were certain other formalities that had to observed, but most of those now crossing our southern border now would be able to do so if the pre-1965 law were still in force. Those from "the Dominion of Canada, Newfoundland, the Republic of Mexico, the Republic of Cuba, the Republic of Haiti, the Dominican Republic, the Canal Zone, and the independent republics of Central and South America" were non-quota immigrants by section 4(c) of the Immigration Act of 1924.

You imply we had open borders with Mexico before 1965, heard of operation wetback?  We did deport illegals from latin america before.  But to be clear, I support strict limits on immigration from low development, high crime, high birthrate countries like mexico.

I sincerely hope for your sake that you don't have any Irish ancestry. After all, the Know Nothings wanted strict limits from low development, high crime, high birthrate countries like Ireland.  But I digress.

I never said the borders were completely open. Immigrants from elsewhere in the Americas were supposed to complete certain formalities that the Mexican government put roadblocks on because they didn't want major emmigration. (There were times when Mexican crops rotted in the fields for lack of labor to harvest them.) The Bracero program was initially an arrangement to get the Mexican government to allow Mexicans to come north on a seasonal basis that allowed for crops on both sides of the border to be harvested in a timely fashion and freed up U.S. manpower to be used in the war effort.

Now it's true that some Mexicans didn't bother with the formalities and others overstayed their time in the Bracero program. It's also the case that the Bracero program was continued at least a decade longer than it should have. However, it's also true that the vast majority of Central American asylum seekers would be admitable as ordinary immigrants if the pre-1965 law were in place.
