It is based on their 2017 voting record, and represents the consensus of experts from about 20 respected environmental and conservation organizations.
A 100 rating is the best possible score. Results for our area: Sen. Michael Bennet (D) 84, Sen. Cory Gardner (R) 0 (zero!), Rep. Scott Tipton (R) 6.
