The Democratic Congressional Campaign Committee is boasting its best August fundraising numbers ever, raking in more than $15.4 million last month, according to figures provided first to Roll Call.

That’s $4.5 million more than the committee’s fundraising total in August 2016, and $5.1 million more than the committee raised in August 2014.  Nearly $7 million of last month’s total came from online donations, with an average donation of $20.

“With the primary season over, there is no question that Democrats’ historic fundraising and grassroots support puts us in a strong position to take back the House,” DCCC Chairman Ben Ray Luján said in a statement.

The New Mexico Democrat has raised concerns about spending from outside Republican groups, and said Democrats “will take nothing for granted.”

The DCCC has raised more than $206 million this campaign cycle, and ended August with $69.8 million on hand.

Monthly fundraising numbers are not necessarily accurate indicators of who will win on Election Day, but Democrats say the fundraising numbers show that their supporters are energized about the upcoming election.
