(CNN) – Many political observers are crediting Democrat Hillary Clinton's surprise win in New Hampshire to the New York senator's rare display of emotion at a Portsmouth Coffee shop Monday morning.

But Clinton's tearful moment failed to win at least one Granite State voter — the very woman who prompted her response in the first place.

Marianne Pernold-Young told CNN Wednesday she ultimately picked Barack Obama in Tuesday night's primary because of the Illinois senator's performance at a recent rally she attended.

"I was moved to tears. Not once, but twice," she said. "And he has this enormous electricity. And I was just taken aback. And I just had to go with my feelings." (Video: Young speaks on American Morning)

On Monday, Young asked Clinton how she was holding up under the rigors of a presidential campaign — an inquiry that cause the presidential candidate's eyes to well up and voice to tremble.

"It's not easy, and I couldn't do it if I just didn't, you know, passionately believe it was the right thing to do," a teary Clinton said. "You know, I have so many opportunities from this country, I just don't want to see us fall backwards." (Video: Clinton gets emotional)

The moment instantly became the most-covered event on the campaign trail on the day before the critical New Hampshire primary, drawing praise from some who said Clinton had finally bared her true self to voters. The next day, Clinton won among voters who said a candidate who "cares about people" is most important (a category John Edwards won in Iowa.)

Young told CNN she herself was touched by the event, though it was not enough to convince her to support Clinton.

"I was very touched and I was totally in awe that she would open up to us, all of us there," Young said. "But it was a delicate matter."

On CNN's American Morning, Clinton wouldn't speculate whether the moment had put her over the top in the Granite State the night before, but said, "I'm really glad that I had a chance to say what I believe with all of my heart, that politics isn't a game, it's not a horse race. It's about people's lives."
