Hillary Clinton Dances With Supporters on the Rope Line in New Hampshire

— -- If Hillary Clinton has any concerns about her campaign, she didn't let on today.

Following her remarks at the New Hampshire Democratic Party annual convention, the Democratic presidential candidate appeared overwhelmed and energized by the reaction from the crowd -- so much so, she did a happy dance with her supporters on the rope line.

"Unbelievable. It is amazing," Clinton told ABC News about the crowd. "It feels great."

During her speech at the convention, where her Democratic opponents Bernie Sanders and Martin O'Malley also delivered remarks, Clinton described herself as a "fighter" who will get things done, and drew contrasts between herself and the Republicans.

"If you want a president who will listen to you, work her heart out to make your life better, and work to make a better, stronger, fairer country, then you're looking at her," Clinton told the crowd to a rousing applause at the Verizon Arena in Manchester.

Clinton also weaved Donald Trump's anti-Muslim questioner controversy into her remarks.

"The way he handled the question about President Obama was shocking, but not surprising," Clinton said, referring to Trump's response to a voter who said that Obama was a Muslim. "He's been trafficking in prejudice and paranoia throughout this campaign."

On Friday, Clinton told reporters Trump's handling of the question was "appalling" and called on the Republican presidential candidate to apologize.
