DAY IN A NUTSHELL
Campaigning in New Hampshire was feverish on the eve of the state's primary. Hillary Clinton appeared emotional as she outlined her reasons for running for the presidency, while polls suggested that her rival - Barack Obama - was taking a commanding lead. Republicans Mitt Romney, John McCain and Mike Huckabee all attended a series of campaign events throughout the state.
"It was interesting in the debate, Senator Clinton saying: 'Don't feed the American people false hopes, get a reality check'... I mean, can you picture JFK saying: 'We can't go to the moon. It's a false hope. Let's get a reality check'? It's not... what our tradition has been."
Barack Obama, speaking on Good Morning America.
"It's not easy, it's not easy, and I couldn't do it if I just didn't passionately believe it was the right thing to do. I have so many opportunities for this country. I don't want to see us all fall back."
Hillary Clinton speaks to voters in Portsmouth, New Hampshire.
"The Republican establishment spent 2007 underestimating Mike Huckabee. If Huckabee does win the nomination, it would be amusing if Democrats made the same mistake in 2008."
William Kristol, New York Times columnist
"It's long past time to bring real change to Washington. That's never going to happen if all we do is send the same people back to Washington to sit in different chairs."
Two polls give Barack Obama 10-point leads over Hillary Clinton in New Hampshire.
A Reuters/C-SPAN/Zogby survey puts Mr Obama on 39%, Mrs Clinton on 29% and John Edwards on 19%.
And a Rasmussen poll gives Mr Obama 38%, compared to 28% for Mrs Clinton and 22% for Mr Edwards.
For the Republicans, the Zogby poll gives John McCain the edge, with 34% to Mitt Romney's 29% and Mike Huckabee's 10%.
But the Rasmussen poll places the top two Republicans neck-and-neck, with Mr McCain on 32% and Mr Romney on 31%.
Hillary Clinton needs to win over people of voting age if she is to hold off the challenge from Barack Obama in New Hampshire.
