Despite initial concerns that former Speaker John A. Boehner's departure would affect fundraising , the National Republican Congressional Committee raised $5.1 million in the first month after he announced his retirement .
Although Boehner didn't actually hand over the gavel until the end of the month, October represented the transition period between him and Speaker Paul D. Ryan, and marked the strongest off-year October of revenue ever for the NRCC, leaving it with $22.9 million in the bank.
The Democratic Congressional Campaign Committee raised $5.4 million in October and has more than $24.4 million cash on hand.
Democrats outraised Republicans on the Senate side, too, with the Democratic Senatorial Campaign Committee raising $3.8 million compared to the National Republican Senatorial Committee's $2.3 million.
Despite his committee being outraised by about $1.5 million, NRSC Chairman Roger Wicker remains optimistic that fundraising will pick up once the crowded presidential field winnows.
