Republicans' problems attracting Hispanic voters have been well-documented. But the party's struggles among minority voters in general extends well beyond its poor performance among Latinos.

Take the newly released Gallup data on Asian Americans, for example. More than twice as many identify as Democrats as do identify as Republicans. A plurality identifies as independents, who when pressed for party leaning, tend to align themselves with Democrats. (The data comes from Gallup tracking surveys throughout 2012.)

President Obama won 73 percent of the Asian-American vote in November, exit poll data show -- up substantially from the 62 percent who supported him in 2008. Asian Americans made up a small but growing share of the electorate, accounting for 3 percent of the vote. Their shift toward Obama was more dramatic than the movement in any other demographic.

As the exit poll data also show, Republicans' struggles among black voters continued in 2012, with Obama winning more than nine in 10 African-American votes for the second time. And, as we've often noted, the president increased his share of the Hispanic vote, winning more than seven in 10 Latino votes.

It's worth noting that those who described their race as something other than black, white, Asian, or Hispanic gravitated away from Obama last year, but a majority (58 percent) still supported him.

As we've noted in this space, adopting a new posture on a single issue (immigration) isn't a cure-all for the GOP's image among Hispanic voters. And even if it were, Republicans would have a ways to go to improve their image among all non-white voters, who accounted for more than a quarter of the electorate in 2012.
