Hopefully never. Most hispanics I've come to know are socialists, very economically liberal and socially authoritarian, especially the women. A lot of them voted for Bush and McCain for their social conservatism, but the Republican Party should leave the core of this demographic alone and pick up the more individualized (conservative) ones. Republicans would be better off to go after asians, as most of them are inherently fiscally conservative.
As Latinos become more assimilated and older generations die off, they will start voting more Republican than they do now. Maybe 50 or 60 years, or possibly never.
I have heard that Latinos actually have a strong distrust of government. They generally are very socially conservative, but Latinos who are born in the United States are more likely to support Republicans than those that aren't. As the younger Latinos enter the voting populace (since more of them were born in America), they will become more Republican as a whole. Of course, for Republicans to win a majority of the Latino vote, we will need to educate them about how our policies are better for them than the Democrats' policies. For example, we are not anti-immigration. We are anti-illegal immigration. I feel that if you want to come to this country in search of a better life, you should at least do it legally. It's a shame that the term "immigration reform" has become such a dirty word in some circles, because reforming the system is exactly what we need. Polls also show that Latinos, especially younger Latinos, are more motivated by economic issues than immigration. To me, it's all about tailoring your message based on your audience.
