Democrats now have a huge advantage with Hispanics across all age groups. According to Gallup in every age group Hispanics are almost twice as likely to lean Democratic than to lean Republican. From Gallup:

Hispanic Party ID, With Independent Leaners Allocated, January-June 2013

It is interesting to see that Republicans do slightly better with young Hispanics than they do with older Hispanics. While many older Hispanics are now committed Democrats, young Hispanics are far more likely to call themselves Independents and are at least slightly more open to listening to the GOP. The poll found that 53 percent of young Hispanics still call themselves Independents even though they lean strongly towards Democrats while only 29 percent of older Hispanics call themselves Independents.

If Democrats are smart they have a real opportunity to lock up this newer generation of Hispanics for decades. Republicans not only risk alienating this group with their stance on immigration but also for the many reasons they are alienating young people of all racial backgrounds.
