I say YES. His environmental record is spotty and often in favor of corporations; he has always been suspect in the eyes of environmentalists. And now the BP disaster---the buck stops with him for not reforming the MMS.
http://en.wikipedia.org/wiki/Ken_Salazarsnip: In 2005, Salazar voted against increasing fuel-efficiency standards (CAFE) for cars and trucks, a vote that the League of Conservation Voters notes is anti-environment. In the same year, Salazar voted against an amendment to repeal tax breaks for ExxonMobil and other major petroleum companies.<6>
In August 2006, Ken Salazar supported fellow Democratic Senator Joe Lieberman in his primary race against Ned Lamont in Connecticut. Lamont, running primarily as an anti-war candidate, won the primary. Salazar's continued support of Lieberman, who successfully ran as an independent against Lamont, has rankled the anti-war wing of the Democratic Party.
In 2006, Salazar voted to end protections that limit offshore oil drilling in Florida's Gulf Coast.<7> snip
Several prominent environmentalist groups are wary of Salazar, noting his strong ties with the coal and mining industries. Kieran Suckling, executive director of Center for Biological Diversity, which tracks endangered species and habitat issues states "He
is a right-of-center Democrat who often favors industry and big agriculture in battles over global warming, fuel efficiency and endangered species."<19> snip
On March 6, 2009 Salazar agreed to move forward with the Fish and Wildlife Service's decision to remove the Rocky Mountain Gray Wolf from the Endangered Species List in Montana and Idaho, but not Wyoming. Minimum recovery goal for wolves in the northern Rocky Mountains is at least 30 breeding pairs and at least 300 wolves for at least three consecutive years, a goal that was attained in 2002 and has been exceeded every year since. (There are currently about 95 breeding pairs and 1,600 wolves in Montana, Idaho, and Wyoming.)<24> Salazar, a former rancher has come under criticism of groups like the Defenders of Wildlife for this decision, and lack of protection of wolves.
On May 9, 2009, Salazar announced the upholding of a Bush-era policy that prevents the regulation of greenhouse gas emissions via the Endangered Species Act (ESA), a policy he pledged to reevaluate when he took office in January. The policy states that, despite the apparent negative impact global warming has on polar bears, an endangered species, greenhouse gasses cannot be regulated with the ESA. Salazar stated in a conference call announcing the decision that "The single greatest threat to the polar bear is the melting of Arctic Sea ice due to climate change," but the Endangered Species Act "is not the appropriate tool for us to deal with what is a global issue." The decision was met with criticism from environmental groups and praise from energy groups including the American Petroleum Institute....more
