CEDAR RAPIDS, Iowa Hillary Clinton raised $38 million during the third quarter of 2015, beating Bernie Sanders' campaign by just $4.4 million.

The former secretary of state's numbers barely outpaced Sanders' despite the fact that 76 percent of Clinton's donations averaged over $200 while 70 percent of Sanders' donations were under $200. Sanders' average donation was just $27.

The Clinton campaign claimed that the $112 million in primary contributions it raised was more than any other non-incumbent primary campaign has brought in.

Clinton's campaign reported spending $35 million in last three months of 2015, meaning she spent money at about the rate she raised it.

The former secretary of state began 2016 with more than $38 million in the bank, according to the campaign's year-end filing with the Federal Election Commission. Her campaign also helped raise about $18 million for the Democratic National Committee and state parties across the country through the Hillary Victory Fund.

"We're heading into the first caucuses and primaries with an organization second to none thanks to the support of hundreds of thousands of people across the country and have the resources necessary to wage a successful campaign in the early states and beyond," said Hillary for America Campaign Manager Robby Mook. "We've focused on investing in people to organize and turn out voters and in preparing for the map to expand beyond the early states."

According to the latest Des Moines Register poll, Clinton leads Sanders by three points going into the Monday night caucus, 45-42 percent. With the difference within the poll's margin of errors, that puts the candidates in a statistical dead heat.
