Now it's South Carolina's turn.

If the Palmetto State, the "First in the South" primary, plays its traditional role in the Republican presidential nomination process, it will be where the White House hopes of virtually every candidate except the eventual nominee will go to die in about 10 days.

It's not for nothing that it's called the "South Carolina Firewall." And at this moment, it's looking like it's Romney's firewall.

Ben Motz of Indiana University looked at NFL games over a 25-year span, and found the home team won 57 percent of the time. Professor Motz did find the home team's winning percentage dropped with the advent of instant replay.

 Voters in New Hampshire today saw Republican candidate Jon Huntsman’s name on their presidential primary ballots. But, it’s unlikely to appear on the ballots of Arizona voters in next month’s state election.  AZPR’s Gillian Ferris Kohl reports, a paperwork error has disqualified Huntsman from appearing on the ballot.

GOP candidate Jon Huntsman got his paperwork in on time yesterday to the Arizona Secretary of State’s office. But it was missing the state mandated signature and seal of a notary public.

With last night's results part of history, the candidates and press turned very quickly to South Carolina, which the AP says "is shaping up to be a dogfight."

And the stakes are high: After winning New Hampshire, Mitt Romney became the first non-incumbent Republican to win the primary season's first two contests, so as Bloomberg puts it, South Carolina, which votes Jan. 21, may be the last chance opponents have to derail Romney.

The United States appears to have resumed drone attacks in Pakistan, specifically in Pakistan's tribal areas, where they've been used to target militants operating along the border with Afghanistan. This strike comes after at least a six-week break in drone strikes. NPR's Julie McCarthy has just finished three years as NPR's Islamabad bureau chief. She's on the line to talk about this.

Hi, Julie.

As expected, GOP presidential candidate Mitt Romney won the New Hampshire primary. Texas Rep. Ron Paul clinched second place — ahead of former Utah Governor Jon Huntsman. Paul told a crowd of supporters that he was nibbling at the heels of the front-runner.

Several decades ago, more than half the states had eugenics laws — measures that allowed governments and others to forcibly sterilize people. It was a difficult chapter for many states and now North Carolina is looking to make amends. A task force says each of the state's 2,000 living victims should receive $50,000.

And today's last word in business is Twinkies in trouble.

UNIDENTIFIED MAN: Ever wonder how they get that creamy filling into the middle of a Twinkies cake? Well, these kids have some pretty good ideas.

UNIDENTIFIED CHILD: First, they put down the creamy filling, then they bake the cake all around.
