Small-dollar donors help power Trump's campaign

Donald Trump likes to boast about his enormous wealth and how he doesn't need anyone else's money to pay for his presidential campaign.

That hasn't stopped tens of thousands of people from chipping in with checks as small as $10 to let the Republican candidate know they're behind him.

Trump has taken in 73,942 contributions - a total that surpasses several of his GOP rivals, despite an early pledge from the billionaire businessman to finance his own campaign.

The fundraising details come from campaign finance reports filed last week.

More than 70 percent of the US$3.9 million he raised from July through September came from people who gave US$200 or less. That small-donor contribution rate is second only to that of Vermont Sen. Bernie Sanders in the Democratic race.
