McCain's Environmental Score: 0

The League of Conservation Voters released their Senate rankings for 2007. This is what their scorecard had to say about John McCain:

Sen. John McCain (R-Ariz.) scored 0 percent in 2007 (24 percent lifetime) due to missing all 15 votes scored, including the key vote on repealing tax giveaways to big oil – a measure that failed by only one vote.

I know that running for election can be time-consuming, but the guy missed 247 votes in 2007, including the one mentioned above, which failed precisely because he failed to deliver on the vote he promised.
