President Obama has been accused of making swift moves on immigration simply to win over the massive and influential Latino vote. But, according to a new Pew Research Center survey, Hispanics aren't even the biggest immigrant group in the U.S. anymore! It's Asians. Approximately 430,000 Asian immigrants made their way to the United States in 2010, making up 36 percent of the new immigrant population compared with Hispanics' 31 percent. Asian-Americans are generally Democratic leaning, and 54 percent of Asian-American voters surveyed said they approve of President Obama's performance—that's 10 percent more approval than he's getting from the general population these days.
