Ron Unz has an article on, among other things, the Sailer Strategy in The American Conservative Magazine. It's a follow-up on his article California and the End of White America,Commentary,November 1999. The new article is Immigration, the Republicans,and the End of White America | The sources of America’s immigration problems—and a possible solution, By Ron Unz, September 21, 2011. You should read the whole thing, but here's a sample, with links added:

"Part of the Bush/Rove political strategy was to take a leading role in passing a sweeping immigration-reform measure, aimed at legalizing the status of many millions of (overwhelmingly Hispanic) illegal immigrants, easing the restrictions on future legal immigration, while also tightening border enforcement. Leaving aside policy matters, the political theory was simple: if the Republican Party changed the laws to benefit Hispanic and other immigrants, these groups and their children would be more likely to vote Republican, thereby helping to solve the GOP’s demographic dilemma. Rove endlessly pointed to 40 percent as the necessary GOP level of future Hispanic support—score above that number and political victory was likely, score much below it and defeat was nearly assured. Although this precise quantitative target was obviously intended for rhetorical effect, it does seem to represent the dominant strain in conservative thinking, namely the need to combine a strong white vote with a solid minority of Hispanics and Asians, thereby allowing the Republicans to survive and win races in an increasingly non-white America. (Meanwhile decades of fruitless efforts to attract a significant share of the black vote would be quietly abandoned.)

But does this political strategy actually make any sense? Or are there far more effective and more plausible paths to continued Republican political success? Although almost totally marginalized within Republican establishment ranks, the anti-immigrationist wing of the conservative movement has maintained a vigorous intellectual presence on the Internet. Over the years, its flagship organ, the VDare.com website run by Peter Brimelow, a former National Review senior editor, has been scathing in its attacks on the so-called Rove Strategy, instead proposing a contrasting approach christened the Sailer Strategy, after Steve Sailer, its primary architect and leading promoter (who has himself frequently written for The American Conservative). In essence, what Sailer proposes is the polar opposite of Rove’s approach, which he often ridicules as being based on a mixture of (probably dishonest) wishful thinking and sheer innumeracy.

Consider, for example, Rove’s oft-repeated mantra that a Republican presidential candidate needs to win something approaching 40 percent of the national Hispanic vote or have no chance of reaching the White House. During the last several election cycles, Hispanic voters represented between 5 and 8 percent of the national total, so the difference between a candidate winning an outstanding 50 percent of that vote and one winning a miserable 30 percent would amount to little more than just a single percentage point of the popular total, completely insignificant based on recent history. Furthermore, presidential races are determined by the electoral college map rather than popular-vote totals, and the overwhelming majority of Hispanics are concentrated either in solidly blue states such as California, New York, Illinois, and New Jersey, or solidly red ones such as Texas and Georgia, reducing their impact to almost nothing. Any Republican fearful of a loss in Texas or Democrat worried about carrying California would be facing a national defeat of epic proportions, in which Hispanic preferences would constitute a trivial component. Pursuing the Hispanic vote for its own sake seems a clear absurdity."

Of course, I don't want to give the impression Unz agrees with us completely. I'll repeat that you  should read the whole thing.

We'll have more to say about this later.
