That won't fly, you see...
Reason 1: generally speaking, Latinos highly prioritize liberal economic policies(Keynesianism), health care, and education. All three of which are on the GOP's "used to support, but now depict as Satanic Communism" list. It also doesn't help that Latinos disproportionately support things like legal abortion and access to birth control. This scares the GOP.
Reason 2: they can't bring themselves to WANT to reach out to Latinos, much less actually change their position to accomodate them. To put it bluntly, the GOP is overwhelmingly white and depends on overwhelming white support, and as the Richwine debacle recently proved, they and their base see Latinos as one step removed from drug-dealing food-stamping vote-rigging welfare-abusing black rapper hood rats. Except they're even more afraid of Latinos in some instances, because of their explosive population growth. This isn't exactly racism, though it often manifests that way, it's more a panicky and nativist sense of impending demographic doom.
Reason 3: they've convinced themselves that they can win over Latinos by giving them hollow lip service and/or simply acknowledging that they exist, and I shit you not, saying things like "I love tacos," and in Rand Paul's case, trying to win them over by professing an admiration for hot-blooded romantic Latino poetry. Instead of, y'know, policy. Not that Democrats don't sometimes do dumb shit like that themselves, but they do it much less often and are certainly less egregious about it.
Reason 4: their idea of crafting policy to attract Latino votes include such gems as advocating for "self-deportation" of Latinos here illegally, and more recently, by pretending to support immigration reform and then poisoning and filibustering the legislation so that it'll never pass, and they get to look good without actually doing anything. That's when they're not moving in the opposite direction, and ramming Voter ID laws through the legislature that disenfranchise Democratic demographics like old people, students, cityfolk, poor people and minorities in order to combat a problem that's practically nonexistent.
