Only 15 percent of nation's 10.2 million undocumented immigrants have lived in the United States for less than five years, reflecting a continued decline in new arrivals and a trend toward that population becoming more embedded in the country, according to a new report.
But Thursday's report from the Pew Hispanic Center is unlikely to temper illegal immigration as a hot topic among Republican hopefuls seeking their party's nod for president. It comes at a time when new front-runner Newt Gingrich is defending his answer at a recent GOP debate in which he argued for finding a way to allow some undocumented immigrants to stay.
Meanwhile, Texas Gov. Rick Perry, who took heat for arguing in favor of his state's policy of offering in-state tuition for undocumented immigrants, has picked up the endorsement of hard-line Maricopa (Ariz.) County Sheriff Joe Arpaio. Arpaio and recently recalled Arizona Senate President Russell Pearce led the charge on that state's controversial enforcement-only immigration law.
