President Barack Obama leaves the White House for Christmas in Hawaii aboard Marine One.

WASHINGTON — On a political high, President Barack Obama capped a bruising year by securing a tax cut for millions of Americans — an achievement that overshadowed Washington's deepening dysfunction and the slow progress of the economy on his watch.

The White House has ended a year with a political victory before. This time around the stakes are higher, and the president is by no means assured of carrying the momentum deep into an election year.

Addressing reporters before heading to Hawaii on Friday, Obama looked like a president in command of the stage again, for now. He left the capital after presiding over a two-month extension of a payroll tax cut — about $40 per paycheck for someone making $50,000 a year — that came when House Republicans caved on demands for a longer deal.

Yet on this issue, like many, enormous work remains for Obama after the new year, just when voters begin choosing a Republican nominee to try to oust him from his job.

Obama initially had pushed for a year-long extension of both the Social Security payroll tax cut and unemployment benefits. He got only two months on both because Congress could not agree on how to pay the bill for more without gutting their own political priorities — the same problem that awaits all sides in the weeks to come.

Although Obama calls a full-year extension a "formality," politically, it is not. So he pushed Congress to work "without drama, without delay" when they return from their own recess.

The whole scene was reminiscent of a year ago, when Obama took a self-described "shellacking" in the midterm elections but still ended up leaving for his yearly Hawaiian holiday on a high note.

In a news conference at the time, a jubilant Obama claimed a "season of progress" after stringing together legislative victories in a lame-duck congressional session, including the repeal of the military's ban on openly gay service members and approval of a new nuclear treaty with Russia.

But progress was short-lived. Obama returned to Washington in January to face a divided Congress and a Republican party prepared to push him to the brink.

This time, Obama left without taking questions from reporters, ensuring no disruption from the narrative all over Washington — a win for him, a capitulation for House Republicans. Had he engaged the press, Obama may well have been challenged about violence in Iraq since a U.S. troop withdrawal, or his own flip-flop over an oil pipeline included in the tax deal.
