I'll give George "Dubya" Bush this: He knew the GOP had no future if did not transform a good number of black Americans into homeowners ("ownership society") and Mexicans into US citizens. Both projects failed spectacularly (one because of greed; the other, sheer racism), and now the GOP is stuck with an aging and undereducated white base that's becoming more hysterical and irrational the more it shrinks.
By 2050, white Americans are expected to become a minority in the United States, while current minorities will become the majority. This does not bode well for a major party that for 50 years coddled the anxieties and fears of white Republicans, particularly Southerners, evangelical Christians and Old Right conservatives.This is why Republican Party leaders have been increasing outreach among Hispanic voters, whom they believe are kindred spirits "by reasons of faith, industriousness and patriotism", says George F Will. That is, culturally speaking. President George W Bush took the idea of a "multicultural GOP" seriously, but his efforts ground to a halt when the US Senate killed his immigration reform bill in 2007. The problem wasn't Democrats. They mostly wanted it. The problem was Republicans. They saw it as wholesale amnesty.
