As Hispanics assimilate (just like the Irish, Italians, and Jews did), they will become part of the white mainstream (at least the majority of Hispanics who have white skin), so America will never truly be majority-minority (or anywhere close to it).
Yeah but most of those groups assimilated during Plessy v. Ferguson which define race by white and black. Those days are long over. If your talking about Cubans and Puerto Ricans assimilating then your right but they were always white there is not much difference between them and peninsular hispanics. What the op meant was Mestizos who are genetically similar to what we call Native Americans. I doubt they will assimilate because 1 Mexico is right there and 2 most want to retain their Mexican/Mesoamerican identity. They will likely if not already go the way of African Americans were they do not assimilate with American culture but American culture assimilate with them. For example American culture has taken so much from African Americans in fashion, music, cuisine, and vernacular especially for a minority group. So much that they complain about cultural appropriation. That is the future of Hispanics Americans. If your are saying that Hispanics climbing up the economical ladder is somehow equivalent to the assimilation of white people that is not only idiotic but insulting.
I don't know about you, but where I've lived (Wisconsin, Northern Illinois, and Southern California), white-mexican dating/marriage is not uncommon. Many of their children will dabble in Mexican culture, but many more probably won't even learn Spanish and may just identify as "white" with the census out of convenience. Some Mexican Americans live on the East Side of L.A., some live in a small town in Iowa, some in the hills of Colorado. They're already a lot more geographically dispersed than the African-American community has ever been, and consequently have different lifestyles, jobs, and economic interests. They don't have the memory of slavery/jim crow and a subsequent Civil Rights Bill to put 90% of them on the same side of the political spectrum. For these reasons, the hispanic vote, even the Mexican-Am vote in particular, is fundamentally different than the black vote, and as a result not monolithic.
