It's taken as a given that American voters in 2012 aren't as concerned about foreign policy as they are the domestic economy.
It's also accepted as true that on matters of foreign policy, President Obama has an advantage over his Republican challenger, former Massachusetts Gov. Mitt Romney, who lacks significant firsthand foreign policy experience.
But Romney has made it a point lately to show that he's not ceding foreign policy and national security to Obama.

Tuesday marks six weeks until Election Day, but registered voters in two dozen states are already able to cast a ballot for president, with more states to allow early voting in the coming weeks.
In the 2000 presidential election, early voting accounted for 15 percent of the total ballots cast. By 2008, that doubled to 30 percent, according to the United States Elections Project at George Mason University. It's expected to be on the rise again this year.

The election is not over, we are told time and time again, and it's not. There are still some 40-plus days to go, there are still debates to be had. It's true that Mitt Romney trails President Obama in most key battleground states, but the margins are in single digits. And, lest we forget, it's not that presidential candidates down in the polls haven't come from behind to win in the past.
Researchers say that springtime snow is melting in the Arctic even faster than Arctic ice. That means less sunlight is reflected off the surface. Bare land absorbs more solar energy, which can contribute to rising temperatures on Earth. Above, a musher races along the Iditarod in the Alaskan tundra in 2007.

This 2005 photo, released by the University of Alaska, Fairbanks, shows how snow-covered Alaskan tundra reflects more light than melted areas. Melting snows means the land can absorb and store more heat and solar energy.
Arctic sea ice is in sharp decline this year: Last week, scientists announced that it hit the lowest point ever measured, shattering the previous record.
But it turns out that's not the most dramatic change in the Arctic. A study by Canadian researchers finds that springtime snow is melting away even faster than Arctic ice. That also has profound implications for the Earth's climate.
