It was a big year for Vermont senator and Democratic presidential candidate Bernie Sanders in terms of bringing in the money to fund his campaign for the White House

First, Sanders received more than 2.5 million individual contributions to beat President Obama's previous fundraising record set in 2011 when he brought in 2.2 million donations. Now it looks like Sanders is bringing in nearly as much money as his biggest rival for the Democratic nomination, Hillary Clinton.

The Associated Press reports that Sanders' campaign raised $33 million over the past three months, compared to $37 million for Clinton. That's some big momentum for Sanders considering that Clinton had beaten him by $35 million in the nine months before that. Also impressive is that Sanders has done it with an average contribution amount of only $27. 

Sanders is still running well behind Clinton in the national polls, but he's close to catching her in Iowa where the first caucus of the 2016 election will be held on Feb. 1. He's reportedly polling ahead of Clinton by a small margin in New Hampshire where the first primary will be held eight days later.
