Massachusetts U.S. Senate candidate Elizabeth Warren (D) raised $ 6.9 million
in the first quarter of 2012, more than doubling the incumbent Sen.
Scott Brown (R-MA), who raised an impressive $ 3.4 million, according to The Hotline.

Aaron Blake:
“The two candidates have agreed to a pact that discourages outside
groups from taking part in their campaign, but their race still promises
to be the most expensive Senate race of the year and possibly the most
expensive ever. That title belongs to the the Hillary Clinton/Rick
Lazio campaign in New York in 2000, when the two combined to raise and
spent $ 70 million. With seven months to go in the 2012 campaign, Brown
and Warren have already combined for $ 35 million — a strong indication
that they may eclipse that race.”
