The League of Conservation Voters this week hit Sen. Elizabeth Dole (R) on her environmental record, adding the first-term lawmaker to the group’s “Dirty Dozen” list for her record on environmental policy.

“Sen. Dole’s record proves that she’s working in the best interests of Exxon/ Mobil, not the people of Raleigh/Durham, for Chevron, not the people of Charlotte [and] for the lobbyists of big oil, not the people of small town North Carolina,” LCV Senior Vice President Tony Massaro said in statement. “Instead of protecting clean water and clean air for our health or developing clean energy for our children, she votes in favor of oil company profits every time.”

The League of Conservation voters’ new list appears as Dole finds herself in an unexpectedly close re-election contest with state Sen. Kay Hagan, whose candidacy the Democratic Senatorial Campaign Committee is supporting with $6 million-plus in television ads in the Tar Heel State.
