Sen. Elizabeth Warren (D-Mass.) is using her campaign email list to fundraise on behalf of another progressive in the U.S. Senate, Jeff Merkley of Oregon.
The Massachusetts senator sent out an appeal Thursday on behalf of Merkley, who is up for reelection in 2014. Merkley seems like a safe bet for reelection.
However, Warren's appeal is significant because it marks new financial and political aid that progressive senators have not previously enjoyed. Warren formed a political action committee, PAC for a Level Playing Field, late last year and solicited donations for it earlier this month.
Warren's 2012 candidacy excited progressives and she raised a whopping $42 million -- more than any other candidate during the cycle. Her email to supporters could lend some of that excitement to Merkley.
