(BOSTON HERALD) — As Mitt Romney prepares for his biggest campaign appearance before a Latino audience, he finds himself hemmed in on an issue of importance to many Latino voters — the future of 11 million children and adults who are in the country illegally.

Romney is boxed from the right by members of his party’s conservative base. Many have been unsettled by his hedged response to President Barack Obama’s new policy to limit deportations of young immigrants, which Gov. Jan Brewer of Arizona and other Republican conservatives have condemned as “back-door amnesty.”

On the other side, Romney faces Latino voters and non-Latino independents whose votes will help elect the next president. But his tough rhetoric on immigration during the GOP primaries — combined with a lingering reputation for reversing course for political benefit — has left Romney with little room to maneuver.
