Because the news media abhor the absence of drama as much as nature supposedly detests vacuums, Rick Santorum's rise in recent polls of likely Iowa Republican presidential primary caucus voters definitely scratches a journalistic itch.

Santorum's ascent to the top three in Iowa polls, along with Mitt Romney and Rep. Ron Paul of Texas, has spiced up the race, especially after the former U.S. senator from Pennsylvania spent so many months stuck in the caboose of GOP candidates.

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.

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.

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.
