Primary Day in New Hampshire turned into open season as GOP rivals launched a barrage of attacks seeking to undermine front-runner Mitt Romney, whose campaign hopes to live up to expectations that he will deliver a solid victory.

Not only does Romney need to win, he needs to win convincingly — holding challengers such as Rick Santorum, Ron Paul, Newt Gingrich and a resurgent Jon Huntsman comfortably at arm's length.

I don't know about you, but when I spoon into store-bought ice cream or chomp into hot dogs, I don't consider it a risky activity, one that could land me in the dentist's chair with a broken tooth. But it turns out that this does happen. Even Costco, the giant warehouse retailer, says it's true.

There are three new hosts of CBS This Morning, which was unveiled yesterday. One is Erica Hill, a holdover from The Early Show, the previous program in the early-morning time slot. Another is Gayle King, still best known as Oprah Winfrey's best friend, who's here to handle most of the entertainment interviews.

In late 2006, Barack Obama held a meeting with his wife Michelle and his advisors to weigh whether he should run for President.

"And Michelle Obama, in front of everybody, asks her husband a very dramatic question," says New York Times Washington correspondent Jodi Kantor. "She says, 'What do you think you can bring to this that the other candidates can't?'"

Her husband paused for a second, and then responded, "I really think if I became President, it would inspire people all over the world to think of new possibilities."

The emotionally charged task of putting price tags on the lives of coal miners killed in the nation's deadliest mine disaster in 40 years continues for a fifth day in West Virginia.

Sources familiar with the mediation talks say the families of 13 Upper Big Branch mine explosion victims are still considering settlement of wrongful death claims with mine owner Alpha Natural Resources.

Six families settled yesterday in mediated negotiations that began Friday at a resort in Glade Springs, W. Va.

At least 30 people were killed at a busy market in northwest Pakistan after a bomb was placed inside the car of a local militia group tasked with fighting against the Taliban.

CNN reports the explosion occurred in the Jamrud Market in the Khyber near the Afghan border. The AP adds:

This may well be the worst story you've come across yet on politics.

Really, I beg you: You should have very, very low expectations for this story.

Pundits, reporters and the campaigns themselves have devoted a lot of energy to setting expectations for the candidates' performances.

Myanmar's upcoming special parliamentary elections just became more legitimate. Aung San Suu Kyi, a leading opposition figure in the country as well as a Nobel Peace Prize laureate, said she will mount a campaign for a seat in parliament.
