ASHEVILLE, N.C. — An environmental group has targeted North Carolina Republican Sen. Elizabeth Dole by putting her on its list of the "Dirty Dozen."

The League of Conservation Voters added Dole to the list Monday because of what political director Tony Massaro calls her poor voting record, and the fact that she's in a close race with Democrat Kay Hagan.

"Senator Dole's record," Massaro said in a statement, "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. For the lobbyists of big oil, not the people of small town North Carolina."

The group's list is bipartisan. Among the dozen: Democratic Sen. Mary Landrieu of Louisiana.

The conservation group has given Dole a lifetime score of 4 percent on environmental votes, Massaro said. Among other things, it cites her opposition to the 2007 Clean Energy Act, which raised vehicle mileage standards. Dole voted against it.
