WASHINGTON — Hillary Clinton’s campaign for president said Friday it raised $37 million in the past three months and more than $112 million in all of 2015 to support her bid for the Democratic nomination.

Clinton’s team also said she raised $18 million for the Democratic National Committee and state Democratic parties nationwide in the fourth quarter. That money would help Clinton in the general election should she win the nomination.

Clinton’s fourth-quarter haul exceeds the $28 million she raised in the three months that ended September 30. Heading into the January sprint toward the leadoff Iowa caucuses on February 1, Clinton’s campaign said it has nearly $38 million in cash on hand.

“Thanks to the hundreds of thousands of Americans who have joined together and powered this historic campaign, we are now heading into Iowa and New Hampshire with the resources we need to be successful,” campaign manager Robby Mook said in a statement.

The Clinton campaign said more than 60 percent of its donors in 2015 were women. It also said 94 percent of the donations it received in the fourth quarter came in increments of $100 or less, but it did not say what percentage of its overall fundraising total came from such small-dollar donors.

In the third quarter, most of Clinton’s money came via traditional fundraising events, where the price of entry was often the legal maximum donation of $2,700. The presidential candidates have until Jan. 31 to report such details to federal regulators.

Clinton isn’t alone in releasing some selective details ahead of that schedule. Earlier this week, Republican Texas Sen. Ted Cruz’s campaign said it had raised nearly $20 million in the fourth quarter.

Cruz’s campaign said in a memo to supporters that he will finish the year having raised over $45 million, but it did not disclose how much the campaign has spent or how much cash it has on hand.
