One of the Democratic Party’s most politically vulnerable senators has established a fundraising link with one of the party’s top prospects to win a Republican-held open seat.

Sen. Blanche Lincoln (Ark.), who is in a tough fight for a third term, and Missouri Secretary of State Robin Carnahan, who’s running to succeed retiring Sen. Kit Bond (R), will be sharing receipts that accrue to the Missouri Arkansas Victory Fund, a joint fundraising committee recently established with the Federal Election Commission.

Lincoln and Carnahan are from neighboring states. Lincoln in 2001 and 2002 served in the Senate with Carnahan’s mother, Jean Carnahan (D).
