ADVANCE FOR SUNDAY, DEC. 29 AND THEREAFTER - FILE - This Feb. 12, 2013 file photo shows President Barack Obama, flanked by Vice President Joe Biden and House Speaker John Boehner of Ohio, giving his State of the Union address during a joint session of Congress on Capitol Hill in Washington. It was a moment for Barack Obama to savor. His second inaugural address over, Obama paused as he strode from the podium last January, turning back for one last glance across the expanse of the National Mall, where a supportive throng stood in the winter chill to witness the launch of his new term. "I want to take a look, one more time," Obama said quietly. "I'm not going to see this again."There was so much Obama could not _ or did not _ see then, as he opened his second term with a confident call to arms and an expansive liberal agenda.
