There are six women incumbents running for reelection in the Senate and five who would be the first female senators in their states, if elected.

Joint fundraising committees are commonly used to help fill the campaign coffers. The money is distributed at the committee's discretion as long as the contributions stay within federal limits.

Adriane Rummel is the treasurer for both committees and is based out of the DSCC’s Washington, D.C., address, according to the FEC filings.
