Washington ? The sixth year of a two-term presidency is rarely kind.

The public’s initial romance with the president has faded. The brief momentum he thought he earned by winning re-election has faded too. The White House doesn’t set the agenda any more; events are in charge now.

For many presidents — Richard M. Nixon, Ronald Reagan, Bill Clinton — this was the point when the scandals took over. President Obama has run into his share of controversies, but none that quite reached scandalhood. (Does anyone even remember the IRS flap?) But the calamitous launch of Obama’s health-care plan has had the same confidence-sapping effect.

And if the past is any predictor, Obama’s plight is likely to get worse before it gets better. The midterm congressional election has almost always taken seats from the second-term president’s party, making his job even harder.

So what are the chances Obama can defy the historical pattern and turn his sixth year into a success?

The obvious portents don’t look good. The president begins 2014 with his popularity near an all-time low in every poll. The health-care mess has shaken voters’ confidence in his competence and his credibility, and those problems aren’t going away soon. If the congressional election were held this month, Republicans might well gain the six seats they need to win a majority in the Senate and control both houses of Congress.

Still, there are reasons to believe Obama’s Year 6 won’t be the disaster his critics predict.

First, the economy is finally recovering in earnest from the Great Recession. A spate of forecasts have predicted growth around a healthy 3 percent this year, with unemployment slowly declining to 6.5 percent.

Presidents get blamed for bad economic news — but they also get credit for good economic news, whether they deserve it or not. And if the recovery brings unemployment down, that will deprive Republicans of one of their main arguments for turning Democrats out of office.

Another potential plus for Obama is that he has finally settled on a central theme that appeals to independent voters as well as Democrats: economic fairness. “Over the course of the next year … that’s where you should expect my administration to focus all our efforts,” the president said last month. “The economy is stronger than it has been in a very long time; our next challenge is to make sure that everybody benefits from that, and not just a few.”

In that vein, Obama plans to wage a major battle to raise the federal minimum wage to $10.10 an hour. The minimum wage is a classic wedge issue, with Democrats and independents supporting Obama’s position, but GOP voters divided.

Obama’s other big domestic priority, immigration reform, works that way too. If he can steer bipartisan legislation through Congress, he’ll take credit. If Republicans block a path to citizenship for immigrants in the country illegally, he’ll make sure they get the blame — especially among Latino voters.

The administration even has reason to hope that opinion on Obamacare, the Affordable Care Act, will shift as millions of once-uninsured people begin to use their new insurance (or their newly won Medicaid).

Foreign policy could also provide a boost thanks to an event that has long been on Obama’s calendar: the withdrawal of most of the remaining 47,000 U.S. troops in Afghanistan. Expect a long series of homecoming ceremonies with flags, marching bands, tearful family reunions — and speeches by Obama reminding voters that he’s fulfilled his 2008 promise to end two wars.

The administration is also trying to negotiate a nuclear deal with Iran (difficult), peace between Israel and the Palestinians (even more difficult) and an end to the civil war in Syria (next to impossible). A win on any would be an unexpected success.

Finally, 2014 is an election year, and Obama has always been better at campaigning than governing.

The president and his allies will be trying to draw the sharpest contrasts they can — on the minimum wage, immigration, healthcare, climate change and everything else — to energize Democratic voters. So the year on

Capitol Hill is likely to be dominated by high-decibel collisions, not bipartisan harmony. If tea party Republicans rise to Obama’s bait as they have in the past, the GOP could suffer in the eyes of many voters.

There’s no guarantee, of course, that things will play out the way Obama would like.

But the president has one bittersweet asset on his side: Unlike during his heady early years in office, expectations for 2014 are low. If he can survive Year 6 with a healthy economy, health care intact, the Senate in Democratic hands and no new disasters, that will look like success and enable him to live and fight another day.
