WASHINGTON (AP) — Declaring the American dream under siege, President Barack Obama called Tuesday night for a flurry of help for a hurting middle class and higher taxes on millionaires, delivering a State of the Union address packed with re-election themes. Restoring a fair shot for all, Obama said, is “the defining issue of our time.”

Obama outlined a vastly different vision for fixing the country than the one pressed by the Republicans challenging him in Congress and fighting to take his job in the November election. He pleaded for an active government that ensures economic fairness for everyone, just as his opponents demand that the government back off and let the free market rule.

ON EDUCATION

Obama offered steps to help students afford college, a plan for more struggling homeowners to refinance their homes and tax cuts for manufacturers. He threw in politically appealing references to accountability, including warning universities they will lose federal aid if they don’t stop tuition from soaring.

ON OSAMA BIN LADEN

Lawmakers leapt to their feet when Obama said near the start of his speech that terrorist leader Osama bin Laden, killed by a raid authorized by the president, will no longer threaten America.

ON THE ECONOMY

At the core of Obama’s address was the improving but deeply wounded economy — the matter still driving Americans’ anxiety and the one likely to determine the next presidency.

“The state of our union is getting stronger,” Obama said, calibrating his words as millions remain unemployed. Implicit in his declaration that the American dream is “within our reach” was the recognition that, after three years of an Obama presidency, the country is not there yet.

“We can do this,” Obama said. “I know we can.” He said Americans are convinced that “Washington is broken,” but he also said it wasn’t too late to cooperate on important matters.

REPUBLICAN REACTION

Republicans were not impressed. They applauded infrequently, though they did cheer when the president quoted “Republican Abraham Lincoln” as saying: “That government should do for people only what they cannot do better by themselves — and no more.”

The speech Tuesday night comes just one week before the Florida Republican primary that could help set the trajectory for the rest of the race.

Romney, caught up in a tight contest with a resurgent Newt Gingrich, commented in advance to Obama’s speech.

Tonight will mark another chapter in the misguided policies of the last three years — and the failed leadership of one man,” Romney said from Florida.
