CAMBRIDGE, Mass. (AP) - Sen. Elizabeth Warren is quickly becoming a prized Democratic campaigning powerhouse, hitting the road on behalf of candidates in key races the party will need to win to retain control of the U.S. Senate in November.
Since March, the Massachusetts Democrat has stumped for candidates in Ohio, Minnesota, Oregon, Washington and Kentucky and has trips planned this week for West Virginia and Michigan.
Along the way, Warren has found her brand of economic populism resonating far from her home in the liberal enclave of Cambridge.
Republicans, however, have pointed out that Warren's views are sometimes an awkward fit in other parts of the country.
They've noted that Warren supports the federal government's efforts to restrict carbon dioxide emissions, restrictions many in Kentucky and West Virginia oppose.
