The League of Conservation Voters has named former Rep. Bob Schaffer (R) to its 2008 “Dirty Dozen” list.

Schaffer is battling Rep. Mark Udall (D) for the right to replace retiring Sen. Wayne Allard (R). The contest is being heavily targeted by Democrats and Republicans — not to mention their surrogates.

In the previous cycle, the left-leaning LCV was successful at helping oust then-House Resources Chairman Richard Pombo (R-Calif.), which the group viewed as a major opponent of its environmental agenda in Congress.

The group spent more than $1 million on ads and personnel in Pombo’s 11th district, beginning early in the 2006 cycle and going through Election Day. Schaffer could be targeted for the same treatment by the group this year.

“Coloradans deserve a senator who works for them, not Big Oil,” LCV Senior Vice President Tony Massaro said in a statement.
