Republican Presidential Candidates Debate in New Hampshire

In New Hampshire last night, and on cable TV, seven Republicans spent two hours denouncing President Obama. How did they distinguish themselves from each other? Did they narrow the field or will other candidates see a chance to jump in? Also, President Obama visits Puerto Rico, in pursuit of votes in Florida. On Reporter's Notebook, will NATO destroy ancient ruins in Libya?
