FILE - In this July 17, 2012, file photo, Massachusetts Democratic candidate for the U.S. Senate Elizabeth Warren waves to voters at the conclusion of a forum at the John F. Kennedy Presidential Library and Museum in Boston. Democrats are counting on their New England friends to help them pick up Republican-held Senate seats on Nov. 6 and construct a barrier against losses in Nebraska and elsewhere that could erase their majority. In Massachusetts, Republican Sen. Scott Brown is suddenly considered the underdog against Warren as the state is poised to easily back President Barack Obama over former Gov. Mitt Romney.
