Ben DeGrow at Schaffer v. Udall is raising questions about the relationship between Mark Udall's campaign and the environmentalist groups attacking Schaffer.

One has to wonder the extent of shady coordination that is occuring between Udall and these left-wing environmentalist groups this year given his past history. In 1998, The Sierra Club was caught "loaning" staff members to Mark Udall's congressional campaign even as Mark Udall's wife was regional representative for the organization. The Rocky Mountain News reported on October 30, 1998:

A Sierra Club  employee who helped write the group's voters guide later was loaned to the congressional campaign of Democrat Mark Udall  , who was endorsed in the guide.

The Sierra Club bills its guide as nonpartisan but Republicans say that clearly is false if one of its authors is now working for Udall .

A Republican group has asked the Federal Election Commission to investigate whether the Sierra Club and the Udall campaign coordinated efforts on the guide.

``That is illegal,'' said Italia Federici, president of the Coalition of Republican Environmental Advocates.

Sierra Club officials said their staffer was not connected with the Udall campaign until after the guide was produced. He still is on the club 's payroll and amounts to an ``in-kind'' contribution to the Udall campaign that will be reported to the FEC.
...
Udall 's wife, Maggie Fox, is a regional representative for the Sierra Club . She took a leave from the organization, using vacation and time she'd earned, to work on the campaign.

Oddly enough, the Udall for Senate campaign is engaged in the same sort of activities as the Udall for Congress campaign was in 1998. I guess old habits die hard.
