Yeah, yeah, we know. Coconut water, beets, meatballs, ethnic food trucks — they were all the rage this year. Lots of people discovered them or rediscovered them and quickly grew to love them.

Congress got plenty of attention this year, but it was for all the wrong reasons.

There were at least three countdowns to shutdown, there was the debt-limit fight, plus the will-they-or-won't-they drama earlier in December over the payroll tax holiday. Looking at how few bills were actually signed into law this year, one might conclude this session was mostly sizzle and not much steak.

"I mean, I knew it was going to be bad this year, but I didn't realize like how bad it was," says Tobin Grant, an associate professor of political science at Southern Illinois University.

The Iraq War may be officially over, but for thousands of Iraqis who fled to America during the conflict, there's no going home. Many left successful careers to settle in Detroit, where finding their future is a challenge.

The U.N. estimates several million Iraqis are now refugees — either inside Iraq or outside the country. Almost 60,000 of them have come to the Detroit metro area since 2006, drawn by the large Arab community that's been there for years.

One of the most important things to understand about global affairs is how much lies beyond any one country's control, even for the most powerful country in the world.

Anthony Cordesman of the Center for Strategic and International Studies says the limits on American power were especially apparent this year.

"American power has always had many real-world limits," he says.

In some ways, he says, that makes President Obama's accomplishments all the more notable.

CEO Eric Treiber walks out onto the factory floor of Chicago White Metal Casting. Workers are busy making aluminum, zinc and magnesium metal parts for cars, swimming pools and farm equipment.

The floor's a lot louder than it was a few years ago. At Chicago White Metal Casting, revenue is up 4 percent from 2010 — and that year was better than the one before.

It's lunchtime at the Barber home in Macon, Ga. Three-year-old Samuel has just gotten up from his nap, and he's hungry for a creamy peanut butter sandwich.

Carol Barber says Samuel eats peanut butter for lunch almost every day. He's not the only one; she has three other little boys.

Millions of Americans love peanut butter sandwiches. It's easy to make, a "kid favorite" and, until now, relatively inexpensive. But in November, the price of peanut butter increased by more than a third.

It's been a week of marathon campaigning for GOP presidential candidate Newt Gingrich: five or six campaign events each day, hitting Rotary meetings, pizza restaurants and coffee shops.

With the caucuses just days away, it's time for closing arguments in Iowa. Gingrich says his argument is that he's a supply-side conservative with experience both in balancing the budget and in making government work.

Even as President Obama relaxes with his family in Hawaii over the holidays, he knows what's on the horizon when he returns to work in Washington.

He will start where he left off, facing new skirmishes with Congress over a push to extend a temporary cut in payroll taxes. That temporary extension was approved just days before Christmas after a high-stakes gamble that finished only after most of Congress had left for the year.

College football is set to enter its final week, and that means the biggest bowl games are coming up. This weekend will see teams such as Auburn, Oklahoma and Georgia Tech in action. And the first week of 2012 will feature marquee matchups like Oregon vs. Wisconsin, and Oklahoma State against Stanford.

Update at 1 p.m. ET: We'll have a separate preview of the BCS title game between Alabama and LSU later this week. Our original post continues:
