WASHINGTON — Vice President Joe Biden will attend a fundraiser in Seattle next month to benefit a new joint fundraising committee created by Sen. Maria Cantwell and three other female Democratic senators up for election this year.
The Oct. 9 event will support Cantwell for Women in the Senate 2014. A Biden spokesman did not have the venue or other details.
The fundraising committee combines Cantwell’s Friends of Maria campaign committee with three others: those for Sens. Mary Landrieu of Louisiana, Kay Hagan of North Carolina and Jeanne Shaheen of New Hampshire.
Democratic control of the Senate is up for grabs this year, and some polls show Republicans have an edge in regaining majority. Democrats now hold 55 Senate seats (two independents caucus with Democrats), and Republicans 45.
Landrieu, Hagan and Shaheen are all running for reelection in November. Hagan and Shaheen, both freshmen, are in competitive races. Landrieu is perhaps the most imperiled among the 21 Democratic incumbents running this year.
Jay Petterson, Cantwell’s campaign treasurer, said the joint fundraising committee was set up last week and did not yet have contributions to report. In addition to the three incumbents, donations to the committee will be spent help elect three other women running for U.S. Senate: Michelle Nunn of Georgia, Alison Lundergan Grimes of Kentucky and Natalie Tennant of West Virginia.
Cantwell, who’s serving her third term, is not up for reelection until 2018.
Correction: An earlier version of this post incorrectly referred to campaign committees of Sens. Maria Cantwell of Washington, Mary Landrieu of Louisiana, Kay Hagan of North Carolina and Jeanne Shaheen of New Hampshire as political action committees. They are campaign committees.
