The League of Conservation Voters has published a scorecard rating members of Congress on how they voted on such issues as offshore oil drilling, protecting the Arctic National Wildlife Refuge, permitting logging in old-growth forests and other environmental issues.

Here's how some of the potential presidential candidates rank according to the percentage of time they voted in Congress for the position favored by the League of Conservation Voters. Only those candidates who have compiled a congressional voting record are included. Candidates with higher scores are the ones who most favor measures to protect the environment and bird habitat.

Is it any wonder people who favor pro-environmental policies in Washington tend to vote for Democrats?

For more information on the records of presidential candidates of both parties on issues relating to birds and their habitats, see the Birders United 2008 Election page.
