House Democrats are touting an August boost to their ground game numbers — in the wake of President Joe Biden dropping his bid for reelection and backing Vice President Kamala Harris.

Staff and volunteers for the Democratic Congressional Campaign Committee knocked on more than 377,700 doors in August — more than in May, June and July combined, according to the committee. The DCCC said 104,000 of those were in the last week of August alone, the most of any week this cycle. House Democrats’ campaign arm also made 845,500 phone calls in August, similarly surpassing the total for the previous three months.

Like others in the party, House Democrats have seen a burst of enthusiasm since Biden ended his reelection bid and Harris launched her run. They’ve experienced a fundraising bump after last month’s convention, too.

“House Democrats are seeing an incredible amount of energy and enthusiasm across the country, and it’s going to power our victory in November,” said DCCC spokesperson Viet Shelton. “We are mobilizing volunteers and connecting with voters in record numbers because, when voters hear our message, Democrats win.”
