Vermont Sen. Bernie Sanders’s fundraising juggernaut outraised Hillary Clinton’s campaign in March, surpassing her for the third consecutive month.

Clinton announced on Monday that her campaign had raised $29.5 million for the month compared with the $44 million raised by the Sanders campaign. Sanders’s March fundraising haul surpasses the campaign’s own record-setting $43.3 million raised in February.

Sanders has made a point to raise a vast majority of his money from small-dollar contributors who donate online — an average of $27 each, according to the campaign. He has also criticized Clinton for devoting time to fundraising from the wealthy.

“What this campaign is doing is bringing together millions of people contributing an average of just $27 each to take on a billionaire class which is so used to buying elections,” Sanders said in a statement on Friday. “Working people standing together are going to propel this campaign to the Democratic nomination and then the White House.”

Clinton has also increasingly emphasized grass-roots fundraising. A majority of Clinton’s donors have given less than $100, according to the campaign. But she also spends a fair amount of time raising millions from larger contributors — including a controversial upcoming fundraiser with actor George Clooney in California with a ticket price of up to $353,400.

She begins April with $29 million in cash on hand for the primary. The Sanders campaign did not disclose the amount of money it had remaining.

Clinton hasn’t always trailed Sanders in fundraising. Up until the end of 2015, Clinton had raised more money and had more cash on hand than Sanders. But beginning in January, Sanders has outraised Clinton each month.

Still, Clinton’s campaign emphasized that despite being outraised and outspent in many states where they competed with Sanders, Clinton now holds a delegate lead that puts her in a strong position to win the nomination.

“By making smart investments and beating our first quarter fundraising goal by nearly 50 percent, we’ve been able to build a nearly insurmountable pledged delegate lead and earned 2.5 million more votes than our opponent,” said Clinton’s campaign manager Robby Mook in a statement.

Mook characterized recent months as bringing a “surge of grassroots support” and he noted that the campaign now has more than 1 million contributors. And the campaign noted that more than $6 million was raised through a joint fundraising committee with the Democratic National Committee and state parties, which the Clinton campaign has said will benefit down ballot Democrats in the general election.
