As I wrote to another friend on FB,

Fact: White people, as a share of the voting population, continue to decline.
Fact: According to the WSJ, Romney lost by almost 40 percentage points among Hispanics, by almost 50 points among Asians and by about 80 points among Black people.

Auguste Comte said it best, "Demographics is destiny". Oh sure, a person can swing things here and there but by and large the statement holds. And while the Republican leadership continue to alienate the fastest growing segments in the population with their exclusionary policies, they will find it increasingly hard to win elections on the national stage. They need a paradigm shift - i.e. give up their reactionary policies on immigration and remember that their own revered Reagan reached a compromise that led to amnesty for the illegal immigrants in the US in the 80s.
