Clinton Fights Back Tears

From CBS News' Fernando Suarez:

PORTSMOUTH, N.H. -- Just days after a poor showing in Iowa and hours after new polls show Hillary Clinton trailing Barack Obama in New Hampshire, it seems the pressures of the campaign have caught up to Clinton.

During a campaign stop with undecided voters at a coffee shop here, Clinton answered a variety of questions ranging from health care to education. But it was the final question that clearly affected Clinton.

She was asked how she gets up every morning and copes with the struggles of running for president. An admittedly tired Clinton answered the question emotionally, at one point welling up during her response.

"It's not easy. And I couldn't do if I just didn't you know passionately believe it was the right thing to do," Clinton told the crowd at Portsmouth's Cafe Espresso.

"This is very personal for me. It's not just political. It's not just public. I see what's happening. And we have to reverse it," she said as her voice began to crack and she held back tears.

"Some people think elections are a game and they think it's like who's up or who's down. It's about our country. It's about our kids; futures. And it's really about all of us together."

"You know some of us put ourselves out there and do this against some pretty difficult odds. And we do it each one of us because we care about our country. But some of us are right some and some of us are wrong. Some of us are ready and some of us are not. Some of us know what we will do on day one and some of us haven't really thought that through enough."

"So, as tired as I am, and I am, and as difficult as it is to keep up what I try to do on the road, like occasionally exercise, try to eat right - it's tough when the easiest food is pizza - I just believe so strongly in who we are as a nation. So i'm going to do everything I can to make my case and you know then the voters get to decide."
