OBAMA LEGACY: Immigration stands as most glaring failure

WASHINGTON (AP) — President Barack Obama's inability to overhaul the nation's immigration system will stand as the most glaring failure in his effort to enact a vision of social change.

Advocates and allies will credit him with embracing a newly aggressive assertion of executive power that, despite last week's Supreme Court deadlock and political opposition, remains a legal pathway for the next president.

The decision left in place an injunction freezing his 2014 executive action, which had expanded his protection of Dreamers and temporarily protected some parents of people with legal status.

"If the Supreme Court had ruled in his favor, he'd probably be remembered as the person who helped to protect half of the undocumented population in the country," said Frank Sharry, founder of the immigration reform group America's Voice.

In 2014, the president declared the administration's limited resources would be focused on removing threats to national security and public safety, and recent arrivals.

"Devising that approach and implementing it has fundamentally changed the way laws are enforced and has had a real impact on communities," said Cecilia Munoz, the president's chief adviser on immigration.
