"Very ironic. Imagine, Texas, New Mexico Arizona and half of California belonging to Mexico."
I don't think that people realize the type of love that the native Texans have for their state. For instance, a native Texan often refers to 'The Republic of Texas', and no state politician every won votes in Texas by expressing a desire to accomodate the would-be overlords on either coast. In other words, it's FAR more likely that Texas would become an independent nation than seeing Texas revert to Mexico.
As for the others: Southern California and New Mexico are both lost, starting with their to radical left-wing politics. As for Arizona, that's probably a borderline case, pardon the pun.
