One steady source of income to Congressional campaigns in this election has been from current members. And they have lots of different ways to give.
Nancy Pelosi rose through the ranks to become the Democrats’ Congressional leader in part because of her fundraising prowess. In this election cycle, for example, she raised more than $2 million for her own campaign.
Sheila Krumholz, who heads the Center for Responsive Politics, says because Pelosi’s re-election is a lock, she can open up her purse strings: "She can then take that money to tithe to the party."
Pelosi can do this by contributing to the party's campaign arm for House members, the Democratic Congressional Campaign Committee. Krumholz says Pelosi will raise funds, "both from her campaign and from her leadership PAC. She will then support other colleagues, junior colleagues, struggling candidates for office."
