A new and massive poll of 2,029 18- to 29-year-olds from Harvard’s Institute of Politics just released found that of those who say they will “definitely be voting,” 51 percent want the GOP in charge, 47 percent favoring Democratic control. The unexpected anti-Democratic swing prompted a Canadian Broadcasting Corporation reporter quizzing poll experts on a media conference call to IOP blurted out, "How did the Democrats and Obama screw this up?"

As you can see the Democratic share of the Latino/Hispanic vote still weighs heavy in favor of Democrats. However, the GOP share of the vote has increased to a level which matched support when President Bush, who was popular with the Hispanic community, was in office. Resulting in a 7% increase in three years without much to little effort by the Republicans in voter outreach to the Hispanic and Latino communities respectively.
Putting all of this into perspective, this does not equate some monumental shift in paradigm by these two demographics. This phenomena appears to be more related to both groups' disgust with the continual incompetency of both the Administration and Democrats on the Hill. Additionally, it has absolutely nothing to do with the GOP being some sort of idea factory that has won them over ideologically. The latter would be asking entirely too much from Republican leadership.
Addendum: There is an interesting point in the above mentioned Pew Research poll which I found on Real Clear Politics.
Only 36 percent of Latino voters would not support a candidate who disagrees with them about immigration policy (even if they agree on most other issues). Fifty-four percent would consider voting for the candidate they disagree with, and 6 percent said it “depends.”
