The Huge Impact of Small-Dollar Donors on Presidential Fundraising

Daniel Moughon, an insurance salesman from Fort Worth, Texas, said he knew long-shot Republican presidential candidate Carly Fiorina was special after listening to one of her early Iowa speeches. He's donated to her 10 times since then.

Moughon is not giving millions, though. He's not even giving thousands.

In fact, he has added just $273 to the former Hewlett-Packard CEO's campaign coffers through small donations ranging from $7 up to $100.

Why Fiorina? "Well, one, you can't trust elected Republicans, they've let us down time after time," Moughon said. "Carly Fiorina has a clear message. She's a true outsider and a true proven leader."
